The Local Employment Dynamics (LED) program is a partnership between the Census Bureau and participating states. As of February 2004, 29 states were partners with the Census Bureau in creating this information. Those 29 states cover about 65 percent of America's workers.
These reports use Quarterly Workforce Indicators (QWIs) from the LED program to focus on two groups of older workers: those who are likely to be receiving pension income (65 and older), and the preretirement group (55–64 years old). People in the preretirement group may collect pensions within the next ten years, but may or may not continue to participate in the labor force.
