I.   File Organization:

     The files in the Residential Housing Patterns directory contain 19 indexes of
     residential housing patterns for each race/ethnicity group and metropolitan
     area/division (as defined on June 6, 2003). There is one record per 
     race/ethnicity group and metropolitan area/division. 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 metropolitan areas/divisions are indicated below.

     Note: Residential Housing Pattern Indexes can only be shown for metropolitan
           areas with a minority population of 100 or more for the group in 
           question.
