Constructed Variables

Constructed variable data sets currently exist for Rounds V-XIV only. In the absence of detailed documentation, the variable labels in each data set describe the contents of the variables.

The number of observations in each data set does not necessarily match the total number of observations in the original data files. For the economics data sets, filter criteria were established so that only families with complete economic information were included. The health data sets used the maximum number of non-missing observations per individual analysis. Thus, the health data sets vary in composition more than do the economics ones.

In the economics data sets, nominal ruble values are those figures that appear in the original data. Real ruble amounts are nominal values that have been adjusted to June 1992 rubles.

The chart below describes the different types of constructed-variable data sets that exist for Rounds V-XIV and the unit of observation for each.
