Harmonized datasets are created to provide comparable research-ready variables. Variables are defined as similarly as possible across all waves and studies. Each dataset combines all available waves from each study; each individual is one record. All variables use intuitive variable names and study-specific variable names are used to indicate significant inter-study differences. Spouse versions of most variables are also created. Variables have been built to account for any survey skip pattern.
