State (ICPSR code)

1850: Both samples
1860: All three samples

All persons.

STATEICP identifies the holding's state of enumeration using the Inter-University Consortium for Political and Social Research (ICPSR) coding scheme. The variable allows ICPSR state data to be easily merged with the Slave samples. The ICPSR scheme orders the states geographically by region.

With one exception, state or territory names represent that state or territory's contemporary political boundaries in 1850 and 1860. Users should familiarize themselves with any historical changes in these boundaries that might affect their research. The exception is the state Virginia. Following IPUMS convention, we identify the Virginia counties that subsequently became part of West Virginia as West Virginia.
