I compared the employment numbers from Census 2000 and CTPP 2000 part 2
for Sangamon County, Illinois and found what looked like an
According to Census 2000, the county had 97,526 employed persons,
whereas according to CTPP 2000 Part 2, the county had 112,023 workers.
I assumed that since these are from the same source, both take care of
the second job and absenteeism factors. Or does CTPP count second jobs
Is the cause of the difference then due to the fact that the Census
number accounts for only those who live in that county whereas CTPP
counts all workers including those who come to work from other counties?
Has anyone had a similar experience with CTPP 2000 Part 2 data?
Any input on this issue would be greatly appreciated.
