WASHINGTON, DC – The US Census Bureau released additional information on Thursday 2020 census results showing an increase in the population of metropolitan areas of the United States compared to ten years ago. Additionally, these decennial results showed the nation’s diversity in how people identify their race and ethnicity.
The white population remained the largest racial or ethnic group in the United States, with 204.3 million people identifying themselves as white only.
“We are delighted to reach this important milestone by providing the first detailed statistics for the 2020 Census,” said Ron Jarmin, Acting Director of the Census Bureau. “We appreciate the patience of the public as Census Bureau staff have worked diligently to process this data and ensure it meets our quality standards.”
These statistics, which come from Summary file of the 2020 census breakdown data (Public Law 94-171), provide a first look at populations for small areas and include information on Hispanic origin, race, age 18 and over, housing occupancy, and group neighborhoods. They represent where people lived on April 1, 2020 and are available to nation, states, and communities up to the block level.
The Census Bureau also published data visualizations, America has stories, and videos to illustrate and explain these data. These resources are available on the 2020 Census results page. Advanced users can access this data on the FTP site.
Today’s release reveals changes in the size and distribution of the population in the United States. The population of metropolitan areas in the United States grew by 9% from 2010 to 2020, so 86% of the population lived in metropolitan areas of the United States in 2020, up from 85% in 2010.
“Many counties in metropolitan areas have experienced growth, especially those in the south and west. However, as we have seen in our annual population estimates, our country is growing more slowly than ever before, ”said Marc Perry, senior demographer at the Census Bureau. “This decline is evident at the local level where approximately 52% of counties in the United States have seen their 2020 census populations decline from their 2010 census populations.”
Highlights of the county and metropolitan area:
- The largest county in the United States in 2020 remains Los Angeles County with more than 10 million inhabitants.
- The largest city (place of business) in the United States in 2020 remains New York with 8.8 million inhabitants.
- 312 of 384 U.S. metropolitan areas grew in population between 2010 and 2020.
- The fastest growing US metropolitan area between the 2010 census and the 2020 census was The Villages, Florida, which grew 39% from around 93,000 people to around 130,000 people.
- 72 US metropolitan areas lost their population from the 2010 census to the 2020 census. The US metropolitan areas with the largest percentage declines were Pine Bluff, AR, and Danville, IL, at -12.5% and -9.1 %, respectively.
A data visualization released today shows the population change at the county level from the 2010 census to the 2020 census. Learn more about the evolution of the population in the history of America Counts, More than half of U.S. counties were smaller in 2020 than in 2010.
The 2020 Census used the two separate questions required (one for Hispanic or Latino origin and one for race) to collect the races and ethnicities of the American population – following the standards established by the United States Office of Management and Budget (OMB) in 1997. Building on our research over the past decade, we improved the design of the two separate questions and updated our data processing and coding procedures for the 2020 Census. This work began in 2015 with research and testing focused on the results of the survey. National content test 2015, and the designs were implemented in the 2018 census test.
The improvements and changes allowed for a more complete and accurate description of how people identify themselves, giving a more accurate picture of how people report their Hispanic origin and race in the context of a two-question format. These changes reveal that the American population is much more multiracial and diverse than what we measured in the past.
We are convinced that the differences in overall racial distributions are largely due to improvements in the design of the two separate questions for the collection and processing of racial data, as well as some demographic changes over the past 10 years.
Today’s release of the 2020 census redistribution data provides new insight into the racial and ethnic makeup of the country following improvements in race and ethnicity question design, processing and coding.
“As the country has developed, we have continued to evolve in how we measure race and ethnicity people who live here, ”said Nicholas Jones, director and senior advisor for research and education on race and ethnicity at the Census Bureau. “Today’s release of 2020 census redistribution data provides new insight into the country’s racial and ethnic makeup and diversity. The improvements we made to the 2020 Census give a more accurate picture of how people identify themselves in response to two separate questions about Hispanic origin and race, revealing that the American population is much more multiracial and more more diverse than what we have measured in the past. “
Highlights of Race and Ethnicity:
- The white population remained the largest racial or ethnic group in the United States, with 204.3 million people identifying themselves as white only. Overall, 235.4 million people reported White alone or in combination with another group. However, the white population alone has declined 8.6% since 2010.
- The population of two or more races (also referred to as the multiracial population) has changed significantly since 2010. The multiracial population was measured at 9 million people in 2010 and now numbered 33.8 million people in 2020, an increase of 276%.
- Multiracial populations “combined” for all racial groups accounted for most of the overall changes in each racial category.
- All breeds alone or in groups combined experienced increases. The Some Other Race alone or in combination (49.9 million) group increased by 129%, overtaking the Black or African American population (46.9 million) as the second largest single breed or in a combined group.
- The next racial populations were Asians singly or in groups (24 million), Native Americans and Alaska Natives singly or in groups (9.7 million), and Native Hawaiians and other Pacific Islanders alone or in groups (9.7 million). group (1.6 million).
- The Hispanic or Latino population, which includes people of all races, was 62.1 million in 2020. The Hispanic or Latino population grew 23%, while the non-Hispanic or Latino population increased by 23%. increased by 4.3% since 2010.
It is important to note that these data comparisons between racial data from the 2020 Census and the 2010 Census should be done with caution, taking into account the improvements we have made to the questions on Hispanic origin and race and status. way we encode what people tell us.
Therefore, the 2020 census data shows different but reasonable and expected distributions from the 2010 census for the white population alone, the population of another race alone or in combination and the multiracial population, especially for people who are ‘identify as both white and Another race.
These results are not surprising because they correspond to those of the Census Bureau expert search and corresponding conclusions over the past decade, particularly with the results on the impacts of the 2015 National Content Test Race and Ethnicity Reporting question format.
The Census Bureau uses several measures to analyze the racial and ethnic diversity from the country.
The Census Bureau uses the Diversity Index (DI) to measure the likelihood that two randomly selected people belong to different racial and ethnic groups.
The ID is limited between 0 and 1. A value of 0 indicates that everyone in the population has the same racial and ethnic characteristics. A value close to 1 indicates that almost everyone in the population has different racial and ethnic characteristics.
We converted the probabilities to percentages to make them easier to interpret. In this format, the DI tells us the luck that two people chosen at random will be from different racial and ethnic groups.
Using the same DI calculation for the redistribution data for 2020 and 2010, the odds of two randomly selected people being from different racial or ethnic groups increased to 61.1% in 2020 from 54.9% in 2010.
In general, the states with the highest DI scores are found in the West (Hawaii, California, and Nevada), the South (Maryland and Texas; as well as the District of Columbia, an equivalent state), and the Northeast ( New York and New Jersey).
Hawaii had the highest DI score in 2020 at 76%, which was slightly higher than 2010 (75.1%).
