Summary:
Not everyone wants or needs to sustain a full Business Geographics system. Access to maps and demographics may not be an ongoing need for many - some people just need to get the basic data about an area of interest. DataPlace, a website sponsored by the Fannie Mae Foundation (and referred to as a “KnowledgePlex Initiative”), does an excellent job of letting you access maps, data and charts for any place in the U.S., and it’s free.
Not everyone wants or needs to sustain a full Business
Geographics system. Access to maps and demographics may not be an
ongoing need for many - some people just need to get the basic data
about an area of interest. DataPlace,
a website sponsored by the
Fannie Mae Foundation (and referred to as a "KnowledgePlex
Initiative"), does an excellent job of letting you access maps, data
and charts for any place in the U.S., and it's free.
The site is oriented toward affordable housing and community
development applications. You can select a specific address, or a city,
or even a census tract if you know its number, and then pick what you
want to know about that location: area overviews, maps, data and
charts, rankings or scatterplots. The default option is an Area
Overview, a sample of which looks like this. (I picked Detroit,
Michigan.)

The overview, which includes more than what is shown above, covers many
demographic variables. Note the little charts to the right of each
variable. You can mouse over the chart and get both a blowup of the
chart and more information on the variable. Below is a population
example.

Moving on to the mapping capability - on the right of the screen above,
you have the ability to select data to map and what thematic colors to
use. I chose to map total population, and selected rust for the color
ramp.

Now you can use the "Search for an indicator" capability to get more
data. Clicking "Search" brings you a whole library of additional data.
Each data source is a hyperlink to even more data.

One thing I like about this site is that it offers tasks you might want
to do if you want information to help you evaluate an area, as shown
below. It suggests stuff you might want to do like compare your
location to other locations, make a map, make a scatterplot, etc.
So far everything I've described is available to any site visitor.
However, you can access more capabilities if you're willing to complete
a free registration. You can save places as favorites and save
indicators to use again in further analysis. Registration also sets you
up to do things like linking counties and aggregating their data. You
can even create custom geographies from those available on the system.
Sometimes free stuff is worth what you pay for it. In this case, free
gets you good looking maps, charts and graphs, and comparisons all in a
good-looking format. These are maps, charts and data that you can
easily use in a report or a presentation that will make you look good.
It even has a help section that shows you how to use the site.
