The Sun Belt is a major geographic region in the United States. It generally spans the Southeast and Southwest portions of the country.

Many researchers define the area as the land south of the 36°30′ north latitude line. This boundary includes states like Alabama, Arizona, Florida, Georgia, and Texas. Some people group Arizona, California, Florida, Nevada, and Texas together. They call these the "Sand States" because of their many beaches and deserts. This region is vital to the nation's economy and population trends.

Various climates define the diverse landscape of the Sun Belt. You can find desert and semi-desert climates in Nevada and Arizona. California features a Mediterranean climate. The Southeast, including states like Mississippi and South Carolina, has a humid subtropical climate. South Florida is categorized as tropical. These different climates support many distinct ecosystems. These include chaparral, deciduous forests, grasslands, and even tropical rainforests. The region also holds extremely high biodiversity. Eight of the ten states in the belt contain between 3,800 and 6,700 different species.

Significant population growth began after World War II. Many people moved there seeking warm and sunny weather. A major turning point was the invention of air conditioning. This technology made summer heat much more comfortable for residents. It also allowed manufacturing and industry to grow in the region. Retirees, known as baby boomers, also moved there in large numbers. Economic opportunities in the South and West drove this migration. People also left the "Rust Belt" or "Frost Belt" due to job declines and high living costs.

Economic industries have shifted and expanded over many decades. The oil industry helped states like Texas and Louisiana grow rapidly. Aerospace and defense industries also boomed near military installations. In recent years, high-tech and "new economy" industries have driven growth. California and Texas are leaders in this area. Both states rank among the top five in the nation for Fortune 500 companies. As of 2023, 12 of the 15 fastest-growing cities in the U.S. were located in the Sun Belt.

Urban centers in the region are massive and influential. Seven of the ten largest metropolitan areas in the U.S. are in the Sun Belt. Los Angeles is the largest, with over 13 million inhabitants. Other major metropolitan areas include Dallas–Fort Worth, Houston, Atlanta, and Miami. Texas and California are expected to be among the most populous states. In 2005, the Census Bureau projected massive growth for these states. They estimated that 88% of U.S. population growth would happen in the Sun Belt between 2000 and 2030.

Despite this success, the region faces serious environmental challenges. Water shortages are a major threat to the future. Rapidly expanding populations in Texas, Georgia, and Florida use a lot of water. In California, communities are planning to build desalination plants. These plants turn seawater into fresh water to prevent crises. The region must also protect endangered species. These include the American crocodile, the Florida panther, and the West Indian manatee.

Protecting these animals is essential for the local ecosystems.

The Sun Belt also plays a major role in American politics. Historically, the region has been more conservative than the rest of the nation. This is partly due to a high percentage of evangelical Christians. However, increasing racial diversity is changing the political landscape. Some states are becoming more competitive in national elections. For example, Joe Biden won Arizona and Georgia in the 2021 Senate elections. In 2024, Donald Trump won Arizona, North Carolina, Nevada, and Georgia. The shifting demographics continue to shape how the region votes.
