Comparing Summary File 1 with Census 2000

2010 Census Same-Sex Household Statistics

When comparing Summary File 1 statistics on same-sex unmarried partners to other

estimates, users should be careful. We noticed that a small number of errors may have

occurred when the data were captured for the questions about relationship to householder

or gender. Due to the small population of same-sex married couples, which are included in

the same-sex unmarried partners statistics in Summary File 1, these data capture errors

may have affected the overall results. The Census Bureau will issue a report later this year

showing both the tabulated counts and alternative estimates accounting for these errors in

the same-sex married couple and unmarried partner populations.

In addition, users should not compare the counts in Summary File 1 to estimates of same

sex couples from the 2009 American Community Survey due to differences in data

collection methods.
