I am analyzing the 1996-2008 CPS Voting and Registration supplements, and have been able to replicate a number of Census reports but had trouble with 2002. I used the iPums data and syntax generating system –
The iPums file shows 87,762,207 reporting voted in the 2002 election (using WTFINL)
Whereas the Census tables show 88,903,000 (last 3 digits not reported) - that table is Table 2-1 on this page http://www.census.gov/hhes/www/socdem…
My calculation of the citizen voting-age population appears to be the same in both iPums and the tables, so the discrepancy appears limited to those reporting to vote.
Any insight in to this apparent discrepancy would be appreciated
