Top coded Variables and Corresponding State Means for Values at and Above the Top code

(Back to the variable appendices index)

In order to protect the confidentiality of respondents, the Census Bureau "Top codes" values at the extreme upper end of many variable distributions. For each variable listed below, amounts higher than the topcode are reported as the state median of all values exceeding the topcode. The first row of each table shows the topcode above which all values were altered, and subsequent rows show the median value of all cases above the topcode for each state.
