List of largest census-designated places in California facts for kids
California is a very large and busy state on the West Coast of the United States. It has the most people living in it compared to any other U.S. state. It's also the third largest state by land area. In 2020, over 39.5 million people called California home! The state covers a huge area of about 155,858 square miles (403,670 square kilometers).
California is split into 58 areas called counties. Within these counties, there are many different communities. Some of these communities are officially recognized as cities, but others are not. These non-city communities are called census-designated places (CDPs).
A census-designated place, or CDP, is a special area that the U.S. Census Bureau defines for gathering information. It's like a town or neighborhood that looks and feels like a city, but it doesn't have its own local government. Instead, it's usually managed by the county it's in. For example, San Francisco is a unique place because it's both a city and a county at the same time. This means it doesn't have any separate CDPs within its borders.
This article focuses on the census-designated places in California that had a population of 10,000 people or more in the 2020 census.
Exploring California's Census-Designated Places
Census-designated places are important because they help us understand how many people live in different parts of California, even if those areas aren't official cities. They are often vibrant communities with their own unique character.
