What does this measure?

The share of people 5 and older in a geographic area who speak a language other than English at home. This includes both people who speak English well and those who do not.

Why is this important?

Language diversity can indicate a growing bilingual or multilingual population. It may also indicate a need for language instruction or bilingual services and communication.

How is our county performing?

In 2014-18, 19% of Berks County residents spoke a language other than English at home, up 6 percentage points since 2000. This was higher than Pennsylvania, at 11%, but less than the U.S., at 21%. Both the state and nation had slightly smaller increases than Berks during this period.

Within the county, the largest percentage of residents who spoke a language other than English at home was highest by far in the Central region, at 46%, up 17 percentage points since 2000. Other regions had less. Over half of the City of Reading's spoke a language other than English at home. This group is up 21 percentage points from 2000.

Compared to Berks County, most of the surrounding counties had less language diversity. Lehigh County is an exception where about a quarter of the population speak a language other than English in their homes. Most counties saw increases in this population since 2000 however they lagged behind Berks, with the exception of Lehigh, which grew by 9 percentage points since 2000.

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.
