The initial map
shows the population below poverty according to
the 2000 census.
As you zoom in
from the regional census tract-level map, block
groups display at 50 miles, and streets at 5
miles. Zoom out to view a nationwide county map.
Additional maps include 2000 census data on
ethnicity, education, and income. Change
maps by clicking the drop-down menu under
"Compare Maps" on the left.
The Hampton
Roads Mapper has been online since 2002.
Until
the launch of
PolicyMap in May 2008, FairData was the only
free publicly available source for nationwide
block group-level
interactive maps
showing
socioeconomic characteristics. We encourage all
users of FairData maps to check out PolicyMap.
To maximize the viewable area, toggle off the

This map
shows block group level median income in 1999
for Delaware, DC, Maryland, and Virginia. It is
derived from Map 4 of the Hampton Roads Mapper.
(Thanks to UCL's
Google Map Creator)
You can
search the map by address in the form above the
map. Query for info from the 2000 census by
clicking the balloon markers. If you need
absolute precision along boundaries, you should
use the Hampton Roads Mapper, as there are
locational discrepancies between the Census
Bureau block group geography and streets as
displayed on the Google map.

In 2006 we
added a link to newly released
DataPlace for
more detailed "build your own" analysis -- (no
block groups, tract-level and higher).
Select the field
DataPlace_Link from the INFO tool
pop-up window for a census tract in the FairData
map and you'll see that tract in a new
DataPlace area
overview window, with links to thematic
maps, and exceptional charts and tables across a
wide range of
datasets. (Click on the links under
"Browse by Topic" in the right corner beneath
the
DataPlace map to quickly change the theme to
another indicator.)
Social Explorer is another excellent source
for tract-level and higher maps and tables from
the 1990 and 2000 census. (In many
instances, the maps are superior to DataPlace
maps because more meaningful thematic
breakpoints are used.)
On the
FairData map, tract lines generally display as
faint white lines overlaying the component block
group boundaries when you check the box
"Census Tract High", then select Redraw.
To zoom to the block group level components of a
tract you have identified in the DataPlace map:
(1) copy the tract number (for example,
51550-0201 displayed via the question mark
button on the DataPlace map ) into the block
group search field on the popup form accessed
with FairData's FIND button (2) remove the
hyphen (and the decimal point, if there is one)
and click "Find". A table with data for the
component block groups will display below the
map.
At a scale of
about 5 miles, block group population counts for
persons living in poverty are displayed in
purple boxes.

Geocoded to block level -- based
on early 2001 registration data in Congressional
District 4 prior to the 2001 redistricting.
Approximately 3% of registered voters are
excluded due to geocoding inaccuracies.
Additional discrepancies between 2001 voter data
and the 2000 census result in some blocks
showing more voters than voting age population.
No adjustments have been made for prison
populations. Precinct boundaries (VTDs) do not
reflect changes made in 2001.Block-level themes
display at 5 miles, political party charts at 3

Includes Summer Food sites from
2001.
Note that unlike the other maps, this thematic
map subdivides the 40% to 60% range into 40% to
50% and 50% to 60% -- facilitating the
identification of potential Summer Food open
site
areas (where at least 50 percent of school age
children are eligible for free or reduced price
school meals).
At a scale of
about 5 miles, counts for the under 19
population below the 185% poverty level
are displayed in purple boxes.
The block group level 185%

USDA Summer Food Map Machine.
Consistent with the USDA dataset and Map
Machine, students under 19 in group housing are
included in the 185% counts.

Map 31 -- Language Minority
(18+ non-English speakers who do not speak
English "very well")
This thematic map shows
voting age non-English speakers who do not
speak English "very well". This category
includes all non-English speakers 18 and
over who speak English "well", "not well", or
"not at all".
At a scale of about 5 miles ,
the number (by block group) of 18+
non-English speaking persons who do not
speak English "very well" is displayed in purple
boxes.
Note:
The language minority map is not directly
comparable to Maps 12 and 13. Those maps show
English proficiency by age for Spanish speakers
as a percentage of the Spanish-speaking
population, rather than as a percentage of the
overall voting age non-English speaking
population. The maps also employ a more
restrictive definition for limited English
-- "speak English not well" or "not at all".
Some official definitions (for instance, Voting
Rights Act Sec. 203 language minority coverage)
extend the term "limited English" to
include persons who "speak English well".
Under these interpretations, just one
category -- "Speak English Very Well" --
defines persons who are considered
proficient in English.
