This measure divides the gross rent as a percentage of household income distribution into two equal parts: one-half of the cases falling below the median gross rent as a percentage of household income and one- half above the median. Median gross rent as a percentage of household income is computed on the basis of a standard distribution. (See the "Median Standard Distributions" section in Appendix A.) Median gross rent as a percentage of household income is rounded to the nearest tenth. (For more information on medians, see "Derived Measures.")

Comparability

Data on gross rent as a percentage of household income in the 2018 ACS should not be compared to Census 2000 gross rent as a percentage of household income data. For Census 2000, tables were not released for total renter-occupied units. The universe in Census 2000 was "specified renter-occupied housing units" whereas the universe in the 2018 ACS is "renter occupied housing units," thus comparisons cannot be made between these two data sets.
