People who are working, but earning at or below the poverty line face numerous obstacles that may make it more difficult for them to improve their status. Like others in poverty, they may find it difficult to meet basic needs for food or shelter, as well as facing challenges in paying for services they may need to stay employed, such as transportation or child care.

In 2020-24, 2% of people, or about 10,140 individuals, employed in Lancaster County had incomes below the poverty line, one percentage point decline from 2015-19. This percentage slightly below Pennsylvania and the nation (both at 3%). Within the City of Lancaster, the percentage of working poor was 7%.

All comparison counties had shares of working poor between 2-3%. York and Chester counties were similar to Lancaster at 2%. Dauphin, Berks, Lebanon and Cumberland were all at 3%.

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 3 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.
