The development of a new geographic coding system for the Continuous Work History Sample

Area of Science:

• Demography
• Statistics
• Labor Economics

Background:

• The Continuous Work History Sample (CWHS) relies on geographic coding to track worker locations.
• Existing geographic coding systems have limitations in accurately representing worker residence.
• Accurate worker location data is crucial for labor market analysis and policy development.

Purpose of the Study:

• To describe the statistical development of an enhanced geographic coding system for the CWHS.
• To assess the operational feasibility of the new coding system through a pilot study.
• To estimate the impact of revised geographic codes on worker distribution data.

Main Methods:

• Statistical development of a new geographic coding algorithm.
• Implementation of a pilot study to test operational aspects of the revised system.
• Analysis of preliminary data to estimate changes in worker geographic distribution.

Main Results:

• The new system is designed for implementation with 1993 data.
• The revised system provides a more accurate residence-based geographic distribution of workers compared to the previous employer-based concept.
• Pilot study results offer preliminary estimates of the impact of the new codes.

Conclusions:

• The developed geographic coding system offers a more precise method for mapping worker residences.
• The new system is expected to improve the accuracy of geographic analyses within the CWHS.
• Further evaluation of the system's impact on long-term data trends is warranted.
