Hi Mara,

I agree with Jonathan that keeping transportation planning boundaries on census tract or block group lines makes many things a little simpler. Note that just following block lines can result in transportation planning boundaries that are cross-county or cross tracts, which can really complicate things when you're trying to calibrate or validate against Census data. There are many MPOs who choose not to for various local reasons though.

Regards,
Josie

I can tell you from 22 years of professional experience with an MPO... The Census Bureau doesn't need (or want) to know about your MPO planning area boundary. Urbanized areas and MSAs, CMSAs, etc are geographic definitions only. The Census Bureau puts them out for general reference purposes, and then other agencies like FHWA and FTA use them for funding allocations etc., or for data gathering (like the BEA and BLS). The Census Bureau stays out of this "political football" territory.

 

My organization (Metroplan in Little Rock, Arkansas) has generally kept our transportation planning boundary on census tract lines to make data analysis, i.e. estimates and projections, a little simpler. But that is of course your organization's option.

Subject: [CTPP] drawing MPO boundaries

 

Hello,

 

We are in the process of drawing a new MPO boundary to reflect changes to the 2010 urbanized area.  There are several options being looked at for exactly how to set the new boundary but we are not currently considering Census geography.  Does an MPO boundary get submitted to the Census bureau, and if so are there requirements to snap it to blocks?
