Place Text Files and Description

The Text files only contain data -- no labels, no table headers, no titles. A description of the contents of the files is provided below and in the "README" file in the Text file directory.

I.   File Organization:

     The files in the Residential Housing Patterns directory contain 19 indexes of
     residential housing patterns for each race/ethnicity group and place.
     There is one record per race/ethnicity group and place. There is one file 
     for each year and each race/ethnicity group and one file for each year with 
     all groups combined. All indexes were calculated using Non-Hispanic Whites as 
     the reference group.  The unit of analysis is the census tract.  The number 
     of race/ethnicity groups and places are indicated below.
