Hi Diana -- I am checking into getting it recorded. There is very high probability we can
get it done.

This is great! I wish I could partake, but this is the day of our annual staff retreat.
Would it be okay if I forward this to a couple of colleagues (one in the Seattle Office of
Housing and one in Seattle/King County Public Health) who use PUMS data?
Also, do you think some kind of reproduction of the webinar/slideshow would be available
after April the 16th?

We are hosting a short session to train users on using the
Minnesota Population Center IPUMS . http://usa.ipums.org/usa/
The IPUMS project provides a
user-friendly approach to using decennial Census and ACS Public User Microdata Samples
(PUMS) including the newest 2005-2007 ACS file and the Census 2000, and many older
decennial census files. These microdata samples are a portion of the full individual
records and include all the variables. The data are NOT pre-tabulated.
If you need a quick tabulation that is not included in a CTPP or a standard Census file
like Summary File 3, or the American FactFinder, then using the microdata may be a
solution for you. The PUMS are restricted to larger geographic units (Public Use Microdata
Area) to protect individual confidentiality.
For example, Nathan Erlbaum from New York State recently wanted to know the the impact of
group quarters population on bicycle commuting. I ran a table using Census 2000 (includes
group quarters) and 2005 ACS (excludes group quarters). Probably I should have compared
2005 ACS to 2006 ACS! By the way, the answer was that group quarters had a large effect on
walking for the mode to work, and not much difference on bicycling.
You do not need to have statistical software installed on your PC. The SDA program in
IPUMS can run simple tabulations, regressions, and logit models. We will learn basic
techniques to select rows and columns, filtering (subsetting), re-grouping variable
classifications (very important for continuous variables like travel time, departure time,
age, income) and even try a simple regression. The on-line software cannot do as
sophisticated variable processing as a system like SAS or S+, but it can provide analysts
with a quick way to examine basic patterns that can be used to design more sophisticated
