That is an excellent idea and maybe a Master’s student would like to do this as a project, and could do a cohort analysis using the 1970, 1980 and 1990  Decennial Census PUMS at IPUMS USA    I don’t know what kind of geographic level would be possible, maybe only at the State level?


Personally, I drove to work in Los Angeles in my first job in the 1970s, and have been commuting by bus (Seattle) and rail (Wash DC) since 1983.  My residential choice has been based on proximity to transit.  J

Sorry to be a crank and perhaps it is because I am personally sandwiched between these two generations and sick of hearing about them both...

Interesting statistics but why compare an older age group with a younger age group and then place a generational label.  I am afraid that, without some context, folks are going to make conclusions that might be more about age differences (an age group at the height of their career vs. an age group at the beginning)?  Generational (cohort) comparisons would be more appropriate if you could compare the Baby boom when they were young to the millenials at the same age.  Not saying there are not differences but I am afraid that these side by side comparisons would lead some (the press) to draw conclusions that are beyond what can be told from the data.

In case you haven’t seen these, we posted new profile sheets that use the 2006-2008 ACS and the 2011-2013 ACS Public Use Microdata Sample. 

In these profiles, Baby Boomers are defined as those born between 1946 and 1964, and Millennials are defined as those born between 1983 and 2000. 


For the 2006-2008 ACS, many of the Millennials were not yet of working age. 

The geography is limited only to those Counties for which PUMA geography has matching boundaries.


I have seen some recent forecasts about declining gasoline prices, so we will see how this impacts the mode to work and auto ownership for younger workers in the near future.
