Census Bureau Releases 2020 Census Household Data for Detailed Race and Ethnicity Groups, Tribes and Villages

"AUGUST 1, 2024 — The U.S. Census Bureau today released 2020 Census counts of households, along with information on household type and tenure (whether the home is owned or rented) for 300 detailed race and ethnicity groups and 1,187 American Indian and Alaska Native tribes and villages. The 2020 Census Detailed Demographic and Housing Characteristics File B (Detailed DHC-B) provides household information based on the race or ethnicity of the householder (the first adult in a household for whom census responses were provided). 

The Detailed DHC-B data are available for the nation, states, counties, places, census tracts and American Indian, Alaska Native and Native Hawaiian (AIANNH) areas.

Today’s data product is the companion product to the Detailed DHC-A, which provided total population and the number of males and females by age for the same detailed groups. The Detailed DHC-A was released in September 2023.

The Detailed DHC-B includes data for the household population only. Group quarters (such as college dormitories, prisons or military barracks) are excluded from this data product.

For more information about what the Detailed DHC-B includes, visit the blog “Understanding the Detailed Demographic and Housing Characteristics File B.”.."

Census Bureau Releases 2020 Census Data for Nearly 1,500 Detailed Race and Ethnicity Groups, Tribes and Villages

"SEPTEMBER 21, 2023 — The U.S. Census Bureau today released 2020 Census population counts and sex-by-age statistics for 300 detailed race and ethnic groups, as well as 1,187 detailed American Indian and Alaska Native (AIAN) tribes and villages.

These data come from the 2020 Census Detailed Demographic and Housing Characteristics File A (Detailed DHC-A). Previously, the Census Bureau released 2020 Census data on the Hispanic or Latino population and major race groups such as White, Black or African American, Asian, etc.

Today’s release adds information on detailed groups within those major categories such as German, Lebanese, Jamaican, Chinese, Native Hawaiian and Mexican — and on AIAN tribes and villages like the Navajo Nation. The release includes information about more than 200 detailed race and ethnic groups not tabulated from previous censuses.

“These 2020 Census data illuminate the rich diversity across our nation,” said Rachel Marks, chief of the Census Bureau’s Racial Statistics Branch. “We have this comprehensive picture thanks to the millions of people who responded to the census and provided their detailed racial, ethnic or tribal identity, and thanks to the stakeholders, researchers and tribal leaders who helped us improve how we collect these detailed data.”

Data Highlights

Among the highlights, the Detailed DHC-A reveals the largest detailed groups within the major race groups and the Hispanic population. For the race groups, data are available for both the race alone population and the race alone or in any combination population. The race alone population represents the minimum number of people who identified as that group. It includes those who reported only one response, such as only Fijian. The race alone or in any combination population represents the maximum number of people who identified as that group. It includes those who reported only one response, such as Fijian, and those who reported multiple responses, such as Fijian and Japanese or Fijian and Black or African American.>>"

2020 Census Statistics Highlight Local Population Changes and Nation’s Racial and Ethnic Diversity

"The U.S. Census Bureau today released additional 2020 Census results showing an increase in the population of U.S. metro areas compared to a decade ago. In addition, these once-a-decade results showed the nation’s diversity in how people identify their race and ethnicity.

“We are excited to reach this milestone of delivering the first detailed statistics from the 2020 Census,” said acting Census Bureau Director Ron Jarmin. “We appreciate the public’s patience as Census Bureau staff worked diligently to process these data and ensure it meets our quality standards."

These statistics, which come from the 2020 Census Redistricting Data (Public Law 94-171) Summary File, provide the first look at populations for small areas and include information on Hispanic origin, race, age 18 and over, housing occupancy and group quarters. They represent where people were living as of April 1, 2020, and are available for the nation, states and communities down to the block level.

The Census Bureau also released data visualizations, America Counts stories, and videos to help illustrate and explain these data. These resources are available on the 2020 Census results page. Advanced users can access these data on the FTP site.

Population Changes Across the Country Since the 2010 Census

Today’s release reveals changes in the size and distribution of the population across the United States. The population of U.S. metro areas grew by 9% from 2010 to 2020, resulting in 86% of the population living in U.S. metro areas in 2020, compared to 85% in 2010.

“Many counties within metro areas saw growth, especially those in the south and west. However, as we’ve been seeing in our annual population estimates, our nation is growing slower than it used to,” said Marc Perry, a senior demographer at the Census Bureau. “This decline is evident at the local level where around 52% of the counties in the United States saw their 2020 Census populations decrease from their 2010 Census populations.”

County and metro area highlights:

• The largest county in the United States in 2020 remains Los Angeles County with over 10 million people.
  
• The largest city (incorporated place) in the United States in 2020 remains New York with 8.8 million people.
• 312 of the 384 U.S. metro areas gained population between 2010 and 2020.
• The fastest-growing U.S. metro area between the 2010 Census and 2020 Census was The Villages, FL, which grew 39% from about 93,000 people to about 130,000 people.
• 72 U.S. metro areas lost population from the 2010 Census to the 2020 Census. The U.S. metro areas with the largest percentage declines were Pine Bluff, AR, and Danville, IL, at -12.5 percent and -9.1 percent, respectively.

A data visualization released today shows the population change at the county level from the 2010 Census to the 2020 Census. Read more about population change in the America Counts story, More Than Half of U.S. Counties Were Smaller in 2020 Than in 2010.,,"

U.S. Census Bureau to Release First Look at Nation's Demographic Characteristics from 2020 Census

"The U.S. Census Bureau by August 16 is set to release in-depth demographic statistics from the 2020 Census that will be used to redraw legislative voting districts. 

These follow the April 26 release of the first results from the 2020 Census, which showed that the total population was 331.4 million. The first release determined each state’s share of the 435 seats in the U.S. House of Representatives.

Aside from showing how the ethnic, racial, and voting age makeup of neighborhoods has changed since the 2010 Census, these detailed data will be used by most state legislatures to redistrict or redraw their political districts for elections.

The August data release will provide the first look at the demographic characteristics of the nation by state, county and city (down to the census block level), including:

• Race and ethnicity.
• Voting-age population.
• Occupied and vacant housing units.
• People living in group quarters like nursing homes, prisons, military barracks and college dorms.

Aside from showing how the ethnic, racial, and voting age makeup of neighborhoods has changed since the 2010 Census, these detailed data will be used by most state legislatures to redistrict or redraw their political districts for elections.

“While the primary purpose of these data is for states to redraw their districts, these statistics will also tell us how many people live in each county, in each city and in each block,” said James Whitehorne, chief of the Census Bureau’s Redistricting and Voting Rights Data Office. “This information will provide a detailed demographic portrait of our nation’s population for communities all across the United States.”

The August release will be in a “legacy” format that governments used in the 2010 and 2000 Censuses. States will use these files to begin their redistricting efforts. By September 30, the Census Bureau will make the same data available online in a more user-friendly format on data.census.gov.

In a new video, James Whitehorne and Nicholas Jones, the Census Bureau’s race/ethnicity Research and Outreach director, discuss what to expect in the upcoming data release...."

2020 Census Apportionment Results

"Apportionment is the process of dividing the 435 memberships, or seats, in the U.S. House of Representatives among the 50 states. At the conclusion of each decennial census, the results are used to calculate the number of seats to which each state is entitled. Each of the 50 states is entitled to a minimum of one seat in the U.S. House of Representatives.

The 2020 Census apportionment population includes the resident population of the 50 states, plus a count of the U.S. military personnel and federal civilian employees living outside the United States (and their dependents living with them) who can be allocated to a home state. The population of the District of Columbia is not included in the apportionment population.

The calculation methods used through most of the 20th century have been based upon the use of a mathematically determined priority listing of states. Adopted by Congress in 1941 and used each census thereafter, the method of equal proportions also results in a listing of the states according to a priority value—calculated by dividing the population of each state by the geometric mean of its current and next seats—that assigns seats 51 through 435. For more information, see Computing Apportionment.
