The percentage of the population in a region that is foreign-born, which includes anyone who is not a U.S. citizen at birth. People who become U.S. citizens through naturalization are considered foreign-born.
Foreign-born Americans and their descendants have historically been a main driver of population growth, and that role will only increase in the future. According to the Pew Research Center, new immigrants and their children and grandchildren accounted for 55% of the U.S. population increase from 1965 to 2015, from 193 million to 324 million. Pew projects the population will grow to 441 million in 2065, and 88% of the increase is linked to future immigrants and their descendants. This measure also is a reflection of the composition of a community, which can offer insight into its levels of diversity.
In 2015-19, 8% of Berks County's population was foreign-born, up 4 percentage points from 2000. This was similar to Pennsylvania, at 7%, and less than the nation, at 14%.
Within the county, the Central region had the highest rate of foreign-born residents at 16%. This was up 7 percentage points from 2000. In the other regions, foreign-born residents represented 6% or less of the population and is largely unchanged since 2000. In the City of Reading, the foreign-born population in 2015-19 was 19%, up 9 percentage points from 2000.
Among neighboring counties, there were smaller foreign-born populations in Schuylkill (2%), Lebanon (4%), and Lancaster (5%). There were larger foreign-born populations in Chester (10%), Montgomery (11%) and Lehigh (12%). The largest increases in this population from 2000 to 2015-19 were in Lehigh, Montgomery, and Chester (up 6, 4, and 4 percentage points respectively), with the other counties increasing by 2 percentage points or less in the same time period.

The multiyear figures are from the Census Bureau's American Community Survey. The bureau combined 5 years of responses to the survey to provide estimates for smaller geographic areas and increase the precision of its estimates. However, because the information came from a survey, the samples responding to the survey were not always large enough to produce reliable results, especially in small geographic areas. CGR has noted on data tables the estimates with relatively large margins of error. Estimates with three asterisks have the largest margins, plus or minus 50% or more of the estimate. Two asterisks mean plus or minus 35%-50%, and one asterisk means plus or minus 20%-35%. For all estimates, the confidence level is 90%, meaning there is 90% probability the true value (if the whole population were surveyed) would be within the margin of error (or confidence interval). The survey provides data on characteristics of the population that used to be collected only during the decennial census. Data for this indicator are released annually in December.
