To help local governments better plan for disaster recovery for their residents, it would helpful to know which areas contained high risk/vulnerable individuals. These individuals might include the elderly, small children, disabled individuals, those who are language isolated, and those who do not have access to a vehicle. Creation of heat maps, or other visualizations of these populations can help emergency management... more »

I am trying to make something for all block groups in a county and noticed that I have to make separate requests for each tract.
A block group looks like:
?get=P0010001&for=block+group:*&in=state:2+county:170+tract:000101
but it would be nice if we could request:
?get=P0010001,GEOID&for=block+group:*&in=state:2+county:170
so without specifying the tract.
The added GEOID (just like NAME) would make make each record unique.... more »

As a developer, I think an API to describe and search for SF1 variables will be very useful.

Usages:
1. http://thedataweb.rm.census.gov/data/2010/sf1/desc/all
returns a JSON array of all SF1 variables and their descriptions.

2. http://thedataweb.rm.census.gov/data/2010/sf1/desc/P0010001
returns information about P0010001 (its name, concept,... more »

Working with the Puget Sound Regional Council, I've modified my acs package for R to allow users to download data directly from the Census ACS API. See http://eglenn.scripts.mit.edu/citystate/2013/02/major-improvements-to-acs-r-sneak-peak-at-version-1-0/ for more info and user guide.

The XML format for the data dictionary is a great start, but it could be a lot better. In particular, the hierarchical structure of the variables is not mapped.

Let's take P012B049: African American female 85 years and over. It's extremely tedious to tease apart that this is the combination of three variables: race, sex, and age group. One of the great features of XML is its hierarchical structure, which makes it easy... more »

Given the dearth of other live examples, I felt like I should post something, though I haven't been able to do a lot of necessary cleanup and polish. It was nice to be able to pull something like this together with just a few hours of work via the Census API, though.

For a given ACS sub-table (anything with an _002E or higher suffix), I'm calling the data for all US counties and dividing... more »
