In 47 states, the county-equivalent entities are counties in Louisiana, they are designated as parishes Virginia has both counties and independent cities Alaska has boroughs, census areas, municipalities and cities and the entire District of Columbia is treated as a single county. is divided into counties or county equivalents for political and administrative purposes and for the census. Further, the measurement of growth for small populations between 20 has added uncertainty due to the Census Bureau’s new “differential privacy” disclosure avoidance procedure that increases the potential for error in measuring small populations and small changes. However, in analyzing county growth rates for Hispanics, we included only those counties with at least 1,000 Hispanics in the 2020 census, because growth rates based on small populations can overemphasize growth in these areas.

For all of these except the growth rate of the Hispanic population, our analysis uses all counties in the U.S. The analysis focuses on several dimensions of Hispanic population and change: Hispanic population size share of the county’s population that is Hispanic growth rate of the Hispanic population and the role of Hispanics in population change for each county. 94-171 files plus additional demographic detail. and Hispanic populations summarized to the county level from these data files for 2020, 2010,, we used STF1a data files which include the same information as the P.L. These datasets provide information from the complete census counts for major races by Hispanic origin for adults and children that cover every census block in the country. The principal data sources are the redistricting data or Public Law 94-171 Summary files, the first subnational data released from each decennial census since 1980. Despite a large population share, New Mexico, which had the ninth-largest Latino population in 2010, dropped to 13th-largest in 2020, after being passed by Georgia, North Carolina, Washington and Pennsylvania.Īs part of our ongoing research on Hispanics in the United States, we analyzed how this group’s geographic dispersion has changed over four decades, 1980-2020, using census counts from this period’s five decennial censuses. In New Mexico, the state’s 1 million Latinos are nearly half of the population (48%). Although the Latino population has grown in each of these states, their share of all U.S. As recently as 1990, 86% of Latinos lived in just nine states (Arizona, California, Colorado, Florida, Illinois, New Jersey, New Mexico, New York and Texas). Latino population has been shifting away from states with historically large Latino populations for decades, a trend that can be seen at the state level. By contrast, the 20 counties with the largest numerical growth in population are home to more than a third of the nation’s Hispanics (22.2 million). Together, these counties have a Hispanic population of only 7.6 million. The vast majority of these counties are not in what have historically been Hispanic population centers. The Hispanic population grew by 50% or more from 2010 to 2020 in 517 of the 1,685 counties with 1,000 or more Hispanics in the 2020 census.
