This will be immensely valuable. First of
all, it has all of the 1980, 1990, 2000 printed volumes which means I can
dispense with about 10 feet of shelving of the printed volumes. Would
anyone be interested in having them? AEP

Subject: [CTPP] IPUMS to access
2005 ACS microdata
Sorry! I
hit the “send” button instead of “save.” I
guess I am having a BAD DAY with email and the CTPP listserv.
The IPUMS site http://usa.ipums.org/usa/sda/ provides an on-line table generator
using the 2005 ACS public use microdata sample, that also allows for other
statistical tests such as correlation, multiple regression, logit/probit
regression. It provides a way to create new variables. And it is
FREE! So, if the Census Bureau is not including the table YOU want in
their standard set, you can create your own table with this tool.
For example, in CTPP, we
have a variable called “Means of Transportation to Work.”
However, in the microdata, this is two questions:
How did this person
usually get to work LAST WEEK? List of methods.
How many people,
including this person, usually rode to work in the car, truck or van, LAST
WEEK? __ persons
To separate “drive
alone” from “carpool” you will need to use both
variables: TRANWORK and CARPOOL
The Public Use Microdata
Sample is a SAMPLE of the ACS sample records, so this is going to be useful
mostly for large geographic units, or national analysis.
So, going back to my
earlier email about “year of entry”, I could use the IPUMS to
analyze the Census 2000 and the 2005 ACS data, and use the values to create a
new variable.
Hope this is of interest
to at least some of you! Have a GREAT WEEKEND!
