The comparison of the ethnic composition of an intermediate care facility with several Hispanic residents and the general population was hindered by the absence of categorization of ethnicity according to the United States Census. If all Hispanic residents of the facility were white, then 55% of the facility population were white, a proportion comparable to the 58.2% white population of the general population. On the other hand, if all the Hispanic residents were not white, then 27.5% of the facility residents were white. In that case, the proportion of white residents of the facility is much less than in the general population. Therefore, a Demographic Coding Form was developed to capture the essential data to make direct comparisons and contrasts with the general population recorded by the United States Census. Since the United States Census records Hispanic ethnic minority status as a separate category independent from all other ethnic groups, the design of experiments to investigate the possible effects of ethnicity on populations wisely incorporates the administration of a Demographic Coding Form to capture the key ethnic data to permit direct comparison with the general population.
