[EL] 2010 Census statistics for all pre-redistricted districts

[Michael McDonald]

We've posted selected 2010 census statistics for all the current
(pre-redistricted) congressional and state legislative districts in the
country. You can obtain the reports for any individual state by following
the state links at http://www.publicmapping.org/resources/state-resources
and then following the "Current Districts" link.

Some highlights:

The average district is over-populated by 0.98% from the ideal population
for its legislative chamber. The average African-American majority VAP
district is under-populated by 12.21% and the average Latino majority VAP
district is under-populated by -.75%. The African-American statistics
conform with the population estimates leading into the 2010 census, but
under-population of the Latino districts may come as a bit of a surprise
given that the community is the fastest growing in the country. What this
may tell us is that the Latino community growth is not in the existing
communities. Demographers that I have spoken with attribute the decline in
the minority communities to two factors: children leaving home and
gentrification. In all, these statistics may indicate that at least in terms
of representation, constituencies are becoming a more racially and
ethnically heterogeneous and that we are un-sorting ourselves as a country.


The most under-populated districts are in the Katrina-ravaged parts of
Louisiana and Mississippi. The top five from most under-populated to least
from their ideal population are:

State	District
LA	State House District 99
LA	State House District 104
LA	State House District 103
MS	State House District 115
LA	State Senate District 2

The most over-populated districts are all found in Nevada. The top five from
most over-populated to least from their ideal population are:

State	District
NV	Assembly District 11
NV	Assembly District 28
NV	Assembly District 6
NV	Assembly District 31
NV	Assembly District 34

The smallest population district is New Hampshire State House District 3,
Coos with a total population of 3,233.
The largest population district is California State Senate District 37 with
a total population of 1,215,876.

If you're having trouble reading these statistics, we've posted this
information here, where you can find a link to an Excel spreadsheet with
these data.

For the true data geeks, we are creating and posting block level databases
of merged election and census data. Some of these election data come from
state governments, others were collected by Stephen Ansolabehere and
Jonathan Rodden.

For these data, see: http://www.publicmapping.org/resources/data   

These datasets are then incorporated into our DistrictBuilder software. Some
organizations are hosting our software for public access to mapping in
selected states, we are rolling out versions that can be loaded into your
own Amazon Web Services account as fast as we can generate databases and
configure the software. For academics, we are hosting free versions for
education purposes only -- teaching and research -- courtesy of Amazon for
Education.
