Micropolitan Area 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 micropolitan area
     (as defined on June 6, 2003).  There is one record per race/ethnicity group 
     and micropolitan area.  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 micropolitan areas are indicated below.
