About DDA Viewer Demographic Profiles and Site Analysis


DDA Viewer Demographic Profile Sets are comprised of a set of 6 demographic profiles for one or more geographic areas.


Census 2010 Census Tracts.  The focus of this section is on demographic profile sets for Census 2010 census tract geographic areas (and their aggregates for multi-tract areas).  DDA Viewer can generate the profile sets for a much wider range of geography.  Census tracts are areas subdividing each county.  73,057 Census 2010 census tracts cover the U.S. wall-to-wall.  Census tracts average 4,000 population.  The Census 2010 vintage census tract boundaries will remain as defined for Census 2010 until updated in 2020 for Census 2020.


The six standard demographic profiles are:


1.ACS 2010 Age-Gender-Race/Ethnicity ( ACS DP-1)

2.ACS 2010 Social Characteristics (ACS DP-2)

3.ACS 2010 Economic Characteristics (ACS DP-3)

4.ACS 2010 Housing Characteristics (ACS DP-4)

5.Census 2010 Demographic Profile

6.Composite/Custom Demographic Profile -- combination of selected items from above.


ACS 2010: American Community Survey (ACS) 2010 5-year estimates Demographic Profiles (DP) (updated annually)


Items included in the Composite/Custom Demographic Profile are defined by the user, selecting from the fields available in the five datasets.


View examples by clicking links in the Selected Demographic Profile Sets (below).


In addition to the standard profile set, current estimates and projections profiles are also available.



Developing insights ... examining demographic patterns and change by neighborhood.

... see how demographics of a single or multi-tract study area change over time.

... select your own study area using DDA Viewer.

... examine "richer demographics" based on the ACS 2010 data not available from Census 2010.

... examine/compare/contrast attributes of individual tracts.

... examine demographics for total area (multi-area apps) and how demographics are changing.


Suppression and Top Coding

Data displayed in Viewer Grid or exported to a file may contain flags/notes regarding the content of a specific cell.

These annotation data are contained in the Demographic Profile Annotation Dataset and not contained in the raw data.


Flags/notes always include a $ symbol.  The $ symbol only appears in a data cell if there is a data flag/note about this cell.


$- indicates that either no sample observations or too few sample observations were available to compute an estimate.

$*** indicates this estimate cannot be computed for other reasons.

$1,000,000 in median housing value indicates estimate is above $1,000,000 (top coded).

$2,000 in gross rent indicates estimate is above $2,000 (top coded).
