The United States is a large federal country in North America composed of 50 states, a federal district, and several territories. It is one of the world's most influential countries in politics, economics, science, military affairs, higher education, media, and popular culture. Its institutions and markets have had global reach for more than a century, and its landscape ranges from Arctic tundra in Alaska to tropical islands in Hawaii and Puerto Rico.

The country is known for its constitutional system, vast internal diversity, and long-running tension between federal power and state autonomy. It is home to major financial, technological, academic, agricultural, and cultural centers, including New York, Washington, Los Angeles, Chicago, Houston, and Silicon Valley. The United States also contains many of the world's best-known national parks, research universities, and transport networks.

The country's significance is inseparable from its contradictions: it has been a center of democratic ideals and civil rights activism while also shaped by settler colonialism, slavery, segregation, and unequal access to wealth and power. Its history includes major waves of immigration, industrial expansion, territorial growth, war, reform, and social movements.

Today, the United States remains a highly urbanized, economically powerful, and demographically diverse country. It plays a central role in global trade, diplomacy, entertainment, innovation, and climate and security debates, while internally grappling with polarization, infrastructure needs, housing costs, healthcare access, and regional inequality.

The lands that now form the United States have been inhabited for thousands of years by Indigenous peoples with diverse languages, governments, economies, and spiritual traditions. These include, among many others, the Haudenosaunee, Cherokee, Navajo, Lakota, Apache, Pueblo peoples, Choctaw, Inuit, Yupik, Tlingit, and many nations across the Pacific, Great Plains, Eastern Woodlands, Southwest, and Arctic regions.

European colonization began in the 16th century and accelerated in the 17th century with Spanish, French, Dutch, and especially British settlements. The British colonies along the Atlantic seaboard developed local assemblies and commercial economies but remained part of the British Empire. Tensions over taxation, representation, and imperial control helped trigger the American Revolution. The Declaration of Independence was adopted in 1776, and the United States secured independence after the Revolutionary War, formally recognized by the Treaty of Paris in 1783.

The Constitution created the modern federal government framework in 1787, with George Washington becoming the first president in 1789. Early national history included territorial expansion, conflict with Native nations, and deepening political conflict over slavery. The Louisiana Purchase in 1803 doubled the country's size. Westward expansion, often described historically as Manifest Destiny, brought settlement, displacement, forced removal of Indigenous peoples, and war with Mexico, after which the U.S. gained large southwestern territories.

The contradiction between democratic language and slavery became central to national politics. The Civil War (1861-1865) erupted after the secession of Southern slaveholding states. Union victory preserved the country and led to the abolition of slavery through the 13th Amendment. Reconstruction briefly expanded political rights for formerly enslaved people, but white supremacist violence and later Jim Crow laws imposed segregation and disenfranchisement across much of the South.

In the late 19th and early 20th centuries, the U.S. industrialized rapidly. Railroads, steel, manufacturing, oil, finance, and mass immigration transformed the economy and cities. Labor struggles, reform movements, and the Progressive Era reshaped public life. The U.S. emerged as a major global power after the Spanish-American War and played decisive roles in both World War I and World War II.

The mid-20th century was marked by the Great Depression, the New Deal, wartime mobilization, suburbanization, the Cold War, and the Civil Rights Movement. Landmark federal legislation in the 1960s challenged legal segregation and protected voting rights. Immigration reforms in 1965 changed the country's demographic patterns, increasing migration from Asia, Latin America, Africa, and the Caribbean.

Recent decades have included deindustrialization in some regions, growth in technology and finance, expanded higher education, and ongoing political realignment. Major events include the end of the Cold War, the September 11, 2001 attacks, wars in Afghanistan and Iraq, the 2008 financial crisis, intensified polarization, the COVID-19 pandemic, and renewed public debates over race, democracy, inequality, climate, and national identity.

The United States occupies a broad portion of North America, bordered by Canada to the north and Mexico to the south, with the Atlantic Ocean to the east and the Pacific Ocean to the west. Alaska lies in the northwest of the continent, while Hawaii is an island state in the central Pacific. The country also includes Caribbean and Pacific territories.

Its physical geography is exceptionally varied. Major regions include the Atlantic and Gulf Coastal Plains, the Appalachian Mountains, the Interior Plains and Great Plains, the Mississippi River basin, the Rocky Mountains, intermountain deserts and plateaus, the Sierra Nevada, the Cascade Range, and Pacific coastal valleys. Alaska adds major glaciated mountains, tundra, boreal forest, and Arctic coastline, while Hawaii is defined by volcanic islands.

The country contains extensive forests, fertile agricultural plains, deserts, wetlands, prairies, mountain systems, and long coastlines. Significant river systems include the Mississippi-Missouri-Ohio network, the Colorado, Columbia, Rio Grande, and Yukon. The Great Lakes, shared with Canada, form one of the largest freshwater systems on Earth.

Natural resources include fertile soils, timber, freshwater, coal, natural gas, petroleum, copper, iron ore, and other minerals, though resource distribution varies strongly by region. Geological activity is especially notable in Alaska, California, Hawaii, and the Pacific Northwest, where tectonic boundaries drive earthquakes, volcanic risk, and mountain building.

Because of its size, the United States spans nearly every major climate type found in the mid-latitudes and tropics, from humid subtropical and humid continental climates to Mediterranean, semi-arid, desert, tundra, and tropical climates.

The topography of the United States is among the most varied of any country.

• Highest point: Denali, Alaska — 6,190 m (20,310 ft)
• Lowest point: Badwater Basin, Death Valley, California — about 86 m (282 ft) below sea level
• Major mountain systems: Alaska Range, Brooks Range, Appalachian Mountains, Rocky Mountains, Sierra Nevada, Cascade Range
• Major plateaus and uplands: Colorado Plateau, Columbia Plateau, Ozark Plateau, Appalachian Plateau
• Major plains: Great Plains, Interior Plains, Atlantic Coastal Plain, Gulf Coastal Plain, Central Valley of California
• Canyons and basins: Grand Canyon, Great Basin, Death Valley, Snake River Canyon, canyonlands of the Colorado Plateau
• Coastal areas: Long Atlantic, Gulf, Pacific, Arctic, and island coastlines with beaches, estuaries, deltas, cliffs, barrier islands, and wetlands
• Flood plains: Extensive flood plains along the Mississippi, Missouri, Ohio, and lower coastal river systems

Relief varies from broad, flat agricultural landscapes in the Midwest to steep alpine terrain in the West and Alaska. Eastern mountain ranges are older and generally lower than western ones, while the Great Plains rise gradually in elevation from east to west. In Hawaii, volcanic cones and lava landscapes dominate many islands.

Topographic diversity has shaped settlement, transport routes, agriculture, water supply, flood risk, and regional culture across the country.

The United States experiences a wide range of weather patterns because of its continental scale, varied topography, and multiple coastlines. Conditions differ dramatically by region and season.

| Climate Aspect | Summary | |---|---| | Köppen climate classification | Multiple classifications nationwide, including humid subtropical, humid continental, Mediterranean, semi-arid, desert, marine west coast, subarctic, tundra, and tropical | | Average temperatures | Vary widely: subtropical warmth in the South and Hawaii, cold continental winters in the North and interior, severe Arctic cold in parts of Alaska, mild coastal conditions in parts of California and the Pacific Northwest | | Rainfall | Heavy in parts of the Southeast, Gulf Coast, Hawaii, and Pacific Northwest; lower in the interior West and desert Southwest | | Snowfall | Common to heavy across much of the North, Rockies, Great Lakes, Alaska, and higher elevations; limited or rare in much of the Deep South and Hawaii | | Humidity | Often high in the East, Southeast, and Gulf Coast; lower in many western interior regions | | Best time to visit | Depends on region and purpose: spring and autumn are often most comfortable in many populated areas |

Seasonal extremes are a regular part of life in many regions. Tornadoes are most associated with the Great Plains, Midwest, and South. Hurricanes affect the Atlantic and Gulf coasts. Wildfires are a recurring risk in the West, especially during dry and windy conditions. Flooding, drought, blizzards, heat waves, cold waves, and severe thunderstorms also occur across different regions.

Because the country spans tropical, temperate, desert, alpine, and Arctic environments, no single national average fully represents U.S. weather. Travelers and researchers usually rely on state- or city-level climate data for practical planning.

The United States is the third most populous country in the world by most current estimates. The 2020 U.S. Census counted 331,449,281 residents, and later national estimates place the population in the mid-330 millions.

Population characteristics include:

• Growth: Long-term growth has come from both natural increase and immigration, though growth rates have generally slowed in recent decades.
• Urbanization: The population is predominantly urban and suburban, with major metropolitan regions along both coasts, the Great Lakes, Texas, Florida, and parts of the Mountain West.
• Age structure: The population includes large working-age cohorts, an aging Baby Boomer generation, and regional variation in median age.
• Gender: Nationally near parity between men and women, with slight variation by age group and region.
• Ethnic and racial composition: The U.S. is highly diverse. Census categories commonly include White, Black or African American, Asian, American Indian and Alaska Native, Native Hawaiian and Other Pacific Islander, people of Hispanic or Latino origin, and people identifying with two or more races.
• Languages: English is the dominant language in public life. Spanish is widely spoken, and many communities use Chinese languages, Tagalog, Vietnamese, Arabic, French, Korean, Russian, Haitian Creole, Portuguese, and Indigenous languages.
• Religions: The country has a Christian majority by broad affiliation, alongside substantial numbers of religiously unaffiliated people and communities practicing Judaism, Islam, Buddhism, Hinduism, Sikhism, and many other faiths.

Socioeconomic conditions vary greatly by state, metropolitan area, race, educational attainment, and immigration history. The United States has world-leading universities and high overall educational attainment in many regions, but also significant disparities in income, health outcomes, employment stability, and access to opportunity.

Median household income, poverty rates, employment conditions, and educational attainment are tracked by the U.S. Census Bureau and other federal agencies, but the most meaningful picture is usually regional rather than national alone.

The United States is a federal presidential constitutional republic. Power is divided between the national government and the 50 states, with additional authority held by local governments such as counties, municipalities, townships, boroughs, parishes, school districts, and special districts.

Federal structure - Executive branch: Led by the President, who serves as head of state and head of government. - Legislative branch: Bicameral Congress, consisting of the Senate and the House of Representatives. - Judicial branch: Headed by the Supreme Court, with lower federal courts beneath it.

Political representation - Each state elects two U.S. senators. - House seats are apportioned by population. - Washington, D.C. has a non-voting delegate in the House and participates in presidential elections through the 23rd Amendment. - U.S. territories have varying forms of representation and local self-government.

Administrative structure - 50 states with their own constitutions and governments - Federal district: Washington, D.C. - Territories: Including Puerto Rico, Guam, the U.S. Virgin Islands, American Samoa, and the Northern Mariana Islands - Tribal governments: Federally recognized Native nations exercise forms of sovereignty and self-government within the U.S. legal framework

Public services Public services are delivered across multiple levels of government and include: - Public education - Law enforcement - Fire protection and emergency response - Courts and corrections - Public health - Transportation planning and maintenance - Social services - Utilities regulation - Environmental protection

The current officeholders change over time; for up-to-date leadership, official federal and state government websites are the best source. The U.S. political system is characterized by regular elections, strong judicial review, extensive administrative agencies, and significant debate over federalism, voting access, taxation, civil liberties, and regulatory power.

The United States has the world's largest economy by nominal GDP according to widely used international measures. Its economy is highly diversified, combining advanced services, finance, technology, manufacturing, energy production, agriculture, logistics, entertainment, healthcare, and higher education.

Major economic centers include: - New York City: finance, media, professional services - California metros and Silicon Valley: technology, entertainment, trade, biotech - Texas metros: energy, logistics, aerospace, technology, manufacturing - Chicago: finance, transport, manufacturing, food processing - Washington region: government, contracting, research, law, nonprofits

The labor market is dominated by service-sector employment, but the U.S. also remains a major manufacturing and agricultural power. It has globally important capital markets, a large consumer base, extensive infrastructure, and strong research capacity driven by universities, federal labs, and private firms.

Important economic strengths include: - Large domestic market - Deep financial system - Reserve-currency status of the U.S. dollar - High research and innovation output - Productive agricultural sector - Extensive higher education and skills base in many regions

Key challenges include: - Income and wealth inequality - High healthcare costs - Housing affordability pressures in many metros - Regional divergence between fast-growing and struggling areas - Infrastructure maintenance needs - Exposure to global supply chain shocks and financial cycles

Cost of living varies enormously. Some of the country's most expensive housing markets are in coastal California, New York, Hawaii, and the Washington region, while parts of the Midwest and South remain relatively less expensive. Median income also varies significantly by state and metro area.

Future development is likely to be shaped by artificial intelligence, semiconductor manufacturing, energy transition, climate adaptation, advanced logistics, biomedical research, and the continued reconfiguration of domestic and global supply chains.

• Technology — A globally dominant sector centered in regions such as Silicon Valley, Seattle, Austin, Boston, and other research corridors. Major strengths include software, semiconductors, cloud computing, AI, cybersecurity, and digital platforms.
• Finance and Insurance — New York is the leading hub, with major activity also in Chicago, Charlotte, San Francisco, and other metros. The country hosts large banks, investment firms, insurers, and capital markets.
• Manufacturing — Still a major national sector despite long-term restructuring. Key outputs include machinery, chemicals, vehicles, aerospace equipment, electronics, pharmaceuticals, and food products.
• Healthcare — One of the largest employment sectors, spanning hospitals, outpatient care, biotech, pharmaceuticals, medical devices, and health administration.
• Agriculture and Food Production — The U.S. is a leading producer of grains, oilseeds, meat, dairy, fruits, and specialty crops, supported by extensive processing and export systems.
• Energy — Includes oil, natural gas, coal, nuclear, hydroelectric, wind, and solar production. Texas, the Gulf Coast, Appalachia, and western states are especially important.
• Aerospace and Defense — Concentrated in states such as Washington, California, Texas, Florida, Virginia, and Alabama. Includes aircraft, spacecraft, defense systems, and federal contracting.
• Retail and E-commerce — A vast domestic consumer market supports large brick-and-mortar chains, logistics networks, warehouses, and digital commerce platforms.
• Construction and Real Estate — Driven by population growth, urban redevelopment, logistics facilities, infrastructure projects, and residential demand.
• Tourism and Hospitality — Major draws include national parks, major cities, beaches, theme parks, cultural landmarks, conventions, and business travel.
• Entertainment and Media — Film, television, music, publishing, gaming, sports, and streaming are major cultural and economic exports.
• Transportation and Logistics — Ports, railroads, trucking, air cargo, pipelines, and warehousing underpin domestic and global trade.

The United States has one of the most productive and technologically advanced agricultural systems in the world. Agriculture varies sharply by region, climate, water availability, and market access.

Major crops - Corn - Soybeans - Wheat - Cotton - Rice - Hay and forage crops - Fruits and nuts, especially in California - Vegetables, potatoes, and specialty crops in multiple states - Sugar beets and sugarcane in selected regions

Livestock and animal agriculture - Cattle and beef production are major industries in the Great Plains, Texas, and western states. - Dairy is important in states such as California, Wisconsin, Idaho, New York, and others. - Poultry is especially significant in the Southeast and parts of the Mid-Atlantic. - Hog production is concentrated in the Midwest and parts of the Southeast.

Fisheries and forestry - Alaska plays an especially important role in commercial fisheries. - Gulf, Atlantic, and Pacific coasts support fisheries and aquaculture in varying forms. - Forestry and timber production are important in the Southeast, Pacific Northwest, Alaska, and parts of the Northeast.

Food production system The country has a large integrated food-processing, cold-chain, transport, storage, and export system. Agricultural output supports both domestic consumption and major export markets.

Organic and specialty farming Organic farming, direct-to-consumer agriculture, vineyards, specialty ranching, greenhouse production, and regenerative practices are present nationwide, though still a minority of total output in many categories.

Key long-term issues include water scarcity in the West, soil conservation, farm labor, commodity price volatility, trade policy, and climate-related risks such as drought, floods, and heat stress.

Housing conditions in the United States differ greatly by region, metro area, and local zoning policy. There is no single national housing market; instead, the country has many local and regional markets with very different price levels, vacancy rates, and building patterns.

Typical housing types - Single-family detached homes dominate much of suburban and small-town America. - Apartments are common in major cities and inner suburbs. - Condominiums are widespread in dense urban and coastal markets. - Townhouses, duplexes, manufactured homes, and accessory dwelling units also play important roles in many regions.

Market conditions - High-demand coastal metros and some Sun Belt cities have faced major affordability pressure. - Fast-growing regions often combine active construction with rising land and insurance costs. - Some older industrial cities and rural areas remain relatively less expensive, though housing quality and local economic conditions vary. - Mortgage interest rates strongly influence affordability nationwide.

Rental market Rental costs vary sharply, with some of the highest rents in places such as New York, San Francisco, Boston, Los Angeles, San Diego, Honolulu, Seattle, and Washington, D.C. Lower rents are often found in smaller metros and parts of the Midwest and South.

Affordable housing Affordable housing is a major public policy issue across much of the country. Common concerns include: - Rent burden and homelessness - Limited supply in high-opportunity areas - Zoning restrictions - Aging housing stock in some regions - Insurance and disaster-recovery costs in hazard-prone regions

Federal, state, and local governments all play roles through subsidized housing, vouchers, tax credits, public housing authorities, and fair housing enforcement. Homeownership remains a central aspiration in U.S. culture, but access differs widely by income, race, age, and geography.

For a country-level article, it is more useful to describe major regions and metropolitan areas than individual neighborhoods.

Major regions - Northeast — Dense urban corridors, older industrial cities, major universities, finance, government, and historic seaports. Includes the Boston-New York-Philadelphia-Washington axis. - Midwest — Great Lakes metros, agricultural heartland, manufacturing legacy, logistics strength, and a mix of large cities and small towns. Chicago is the largest hub. - South — The country's most populous broad region by Census definition, with rapid growth in Texas, Florida, Georgia, and the Carolinas. Economically diverse, with strong energy, logistics, healthcare, military, and service sectors. - West — Includes the Mountain West, Pacific states, Alaska, and Hawaii. Known for major technology centers, public lands, ports, tourism, water constraints, and dramatic landscapes.

Major metropolitan areas - New York metropolitan area — The nation's largest metro region; global center for finance, media, commerce, and immigration. - Los Angeles metropolitan area — Major center for entertainment, trade, manufacturing, design, and diverse immigrant communities. - Chicago metropolitan area — Historic rail and logistics hub with strong finance, education, healthcare, and manufacturing sectors. - Dallas-Fort Worth — Fast-growing business and transport center with major corporate relocations and logistics infrastructure. - Houston — Energy capital with major port activity, medical institutions, and aerospace links. - Washington metropolitan area — Federal government center with large professional, research, and nonprofit sectors. - San Francisco Bay Area — High-impact technology and venture capital hub with major universities and severe housing costs. - Miami metropolitan area — Gateway to Latin America and the Caribbean, with finance, trade, tourism, and migration significance. - Atlanta — Major transportation, corporate, media, and higher education center in the Southeast. - Phoenix — Rapid-growth desert metro with logistics, technology, construction, and retirement-related development.

Regional identity in the United States is strong, and local culture often matters as much as state lines in shaping food, speech, politics, architecture, and everyday life.

The United States has one of the world's largest transportation networks, though service quality and mode choice vary greatly by region.

Roads and highways - The Interstate Highway System forms the backbone of long-distance road travel and freight movement. - Extensive federal, state, and local road networks connect urban, suburban, and rural areas. - Car ownership is central to daily mobility in much of the country.

Public transit - Public transit is strongest in older and denser metros such as New York, Washington, Chicago, Boston, San Francisco, and Philadelphia. - Systems include buses, commuter rail, rapid transit, light rail, streetcars, and ferries. - Coverage is often limited in suburban and rural areas.

Rail - Amtrak provides intercity passenger rail, especially useful in the Northeast Corridor and selected state-supported routes. - Freight rail is a major national strength; the U.S. has one of the world's largest freight rail systems.

Airports - The country is served by a vast aviation network including major global hubs such as Atlanta, Dallas/Fort Worth, Denver, Chicago O'Hare, Los Angeles, New York JFK, and others. - Regional airports connect smaller cities and remote areas, including critical service in Alaska.

Ports and waterways - Major seaports include Los Angeles, Long Beach, New York-New Jersey, Savannah, Houston, Seattle-Tacoma, and others. - Inland waterways, especially the Mississippi River system and Great Lakes-St. Lawrence system, are important for bulk freight.

Walking, cycling, and micromobility - Walkability varies widely by city and neighborhood. - Bicycle infrastructure is strongest in selected metros and university towns, though expanding in many places. - Shared bikes, scooters, taxis, and rideshare services are common in urban areas.

EV charging - Electric vehicle charging infrastructure is expanding nationwide, supported by both public and private investment, though availability remains uneven between metropolitan and rural areas.

Transportation access in the U.S. depends heavily on location: some residents can rely on rail and transit, while many others depend almost entirely on personal vehicles.

The United States has extensive national infrastructure, but its quality and resilience vary by region, age, investment level, and exposure to climate and natural hazards.

Electricity - A large interconnected power system serves most of the country through the Eastern, Western, and Texas grids, with additional isolated systems in Alaska, Hawaii, and some territories. - Generation comes from natural gas, nuclear, coal, hydroelectric, wind, solar, and other sources. - Reliability is generally high but can be affected by storms, wildfires, heat waves, and aging equipment.

Water and sewer - Most urban and suburban residents are served by municipal water and wastewater systems. - Rural areas may rely on wells and septic systems. - Common challenges include aging pipes, lead service lines in some communities, drought stress, flood contamination risk, and treatment upgrades.

Internet and broadband - Broadband access is widespread in urban and suburban areas, with cable, fiber, fixed wireless, and mobile options. - Rural and tribal areas often face weaker coverage, lower speeds, or higher costs. - Federal and state programs continue to target digital access gaps.

Cellular networks - Nationwide mobile coverage is extensive, led by major private carriers. - Coverage can be limited in remote mountainous, desert, forested, or Arctic areas.

Other infrastructure considerations - Dams, levees, ports, airports, pipelines, rail corridors, bridges, and public buildings are all major components of the national system. - Maintenance backlogs and modernization needs are recurring policy issues. - Climate resilience is increasingly important for coastal protection, wildfire mitigation, grid hardening, water management, and heat adaptation.

Infrastructure capacity is generally strong by global standards, but the gap between high-performing regions and underinvested systems remains a major national challenge.

The United States has one of the largest and most diverse education systems in the world, including public, private, nonprofit, and for-profit institutions. Governance is decentralized: states and local school districts play major roles in K-12 education, while higher education includes public universities, private universities, liberal arts colleges, community colleges, and vocational institutions.

Higher education and research Notable institutions include: - Harvard University - Massachusetts Institute of Technology (MIT) - Stanford University - University of California, Berkeley - University of Michigan - Columbia University - University of Texas at Austin - Arizona State University

These represent only a small share of the country's many important colleges and universities, which also include large public systems such as the University of California, State University of New York, University of North Carolina, and many land-grant universities.

Community colleges and vocational education Community colleges and technical schools are central to workforce training, transfer education, adult learning, and regional access. Examples include: - Miami Dade College - Northern Virginia Community College - Houston Community College - City Colleges of Chicago

K-12 education Public schooling is primarily organized through local districts under state law. The country has many notable secondary schools, but systems differ greatly by place. Large districts include New York City Public Schools, Los Angeles Unified School District, and Chicago Public Schools.

Libraries and public learning Public libraries are major civic institutions across the country. Notable systems include: - Library of Congress - New York Public Library - Boston Public Library - Los Angeles Public Library

The U.S. education landscape combines globally prominent research institutions with unequal school funding, uneven outcomes, and major ongoing debates about affordability, curriculum, student debt, teacher staffing, and access to early childhood and postsecondary education.

Local Organizations

The United States has a very large and decentralized civic sector. Important categories of local and national organizations that shape community life include:

• Chambers of commerce
• U.S. Chamber of Commerce serves as a major national business association.
• Most cities and counties also have their own local chambers supporting small business, networking, and advocacy.
• United Way network
• United Way operates through many local chapters focused on education, financial stability, and health.
• Rotary and Lions clubs
• Rotary Clubs and Lions Clubs are widespread in towns and cities across the country, often supporting scholarships, health drives, and local service projects.
• YMCA and YWCA
• Present in many metropolitan and regional communities, providing youth programs, recreation, and family support services.
• Community foundations
• Thousands of place-based foundations fund local arts, housing, social services, and education.
• Faith-based organizations
• Churches, synagogues, mosques, temples, and interfaith networks often run food pantries, shelters, and neighborhood support programs.
• Nonprofit service providers
• Organizations focused on homelessness, immigration, disability services, senior care, public health, legal aid, and youth mentoring operate in nearly every state.
• Volunteer and mutual-aid groups
• Food banks, disaster response groups, neighborhood associations, and local volunteer coalitions are common.
• National nonprofit networks with local chapters
• Examples include the American Red Cross, Boys & Girls Clubs of America, Habitat for Humanity, Girl Scouts, and 4-H.

Emergency numbers

• 911 — primary emergency number for police, fire, and ambulance throughout the United States.
• 988 — Suicide & Crisis Lifeline for mental health crisis support.
• In some communities, 311 is used for non-emergency municipal services.

General safety overview

• Major urban areas may experience higher rates of certain crimes such as theft, burglary, car break-ins, and assault in specific districts.
• Suburban and rural areas often report lower overall crime levels, though risks can still include drug-related crime, domestic violence, property crime, and traffic incidents.
• Weather and natural hazards are important safety concerns in many parts of the U.S., including hurricanes, tornadoes, floods, wildfires, winter storms, heat waves, and earthquakes.

Safety tips for visitors

• Use normal urban awareness in busy downtowns, nightlife areas, and transit hubs.
• Do not leave valuables visible in parked cars.
• Follow local guidance for wildfire, storm, flood, and heat advisories.
• In national parks and wilderness areas, prepare for terrain, wildlife, and changing weather.
• Respect private property and local laws, which may differ by state.
