||The data dictionary is a documentation table produced by ERF for each data set. It presents the ERF set of harmonized variables and harmonization standards/concepts on the household as well as the individual levels.
The table's fields indicate the variables' names and labels, as appearing in the data file, a description of the content of each variable, general and country specific comments, and the formula used to generate the variable if computed by ERF. In addition, the data dictionary provides a variable by variable mapping between the original and the standardized values to indicate how each variable was generated, followed by a column illustrating the variable universe and a key column denoting the
availability of the variable in the harmonized data set.
