![]() In both 18, the United States census contained two population schedules. Subsets of each of the three oversamples were included in the 1900 general sample.Ĭodebook, data ( Alaska and Hawaii), and SPSS command files ( Alaska and Hawaii) These datasets were produced as part of the project to create a new 1900 1-in-100 general sample. All populations were enumerated on special schedules, each of which contained several unique questions. The Minnesota Population Center created these 20% samples of the populations of Alaska, Hawaii, and the American Indian population. Request the 1900 1% sample with oversamples. NOTE: with the exception of several variables particular to the Alaskan, Hawaiian, and American Indian schedules, the data below is now available via the IPUMS extract system. Oversamples of Alaskan, Hawaiian, and American Indian Populations in 1900 We provide it here for users who might need to replicate earlier analyses. When we released our own 1-in-100 sample from the 1900 census, we retired the IPUMS version of the 1900 Preston sample from the IPUMS extract system. Variable names and labels are generally identical to those in the current 1900 IPUMS sample, as are all of the IPUMS family inter-relationship variables. ![]() The version above is different from the one available at ICPSR, however, in that our version has been made to be compatible with the other IPUMS datasets. The core data is also available as ICPSR dataset 7825. This 1-in-760 sample was first produced by Samuel Preston and Robert Higgs at the University of Washington in 1980. Below we have provided links to IPUMS datasets that are not available via the extraction system.ġ900 "Preston" sample data file ( ip19002.dat) and command files for SPSS ( ip19002.sps), SAS ( ip19002.sas), and Stata ( ip19002.do and ip19002.dct). Users needing a complete dataset should register for the extract system and simply request all variables from any given year or years. Samples of the United States population censuses of 1850-2010 are available via the IPUMS extract system.
