Data Limitations

The NLMS is based on specific survey months of the Current Population Survey, the Annual Social and Economic Supplement, and a subset of the 1980 Census. These are one-time data collection processes with no subsequent data collection follow up.  Therefore, one limitation of NLMS data is that they provide a one-time only, baseline, measurement of subjects in a long-term follow-up situation. Another limitation of these data is that, although the CPS and census instruments do provide extensive data collection capabilities in specific subject matter areas, desirable general or specific health information is not collected, and smoking status is available on only a limited number of records.
