This article also used data from the Cross-sectional Amish Population & Environment Database 2010s. However, CAPED data is governed under a restrictive privacy rule and an anonymized public-use file is not yet available. As such, this replication file only provides replication code for estimates derived from ACS data.
To access the specific data, download an ACS extract from IPUMS restricted to individuals whose language at home (language) is German, Pennsylvania Dutch, Dutch, or Swiss.
