Total Nonfarm Job Openings are a measure of all jobs that are not filled on the last business day of the month. A job is considered open if a specific position exists and there is work available for it, the job can be started within 30 days, and there is active recruiting for the position.

Total Nonfarm Job Openings are measured by the Job Openings and Labor Turnover Survey (JOLTS) and published by the Bureau of Labor Statistics (BLS). These data are a unique economic indicator of unmet demand for labor and labor shortages. Economists, government officials, and researchers use Job Openings as a measure of tightness within job markets.

Note that the set of available job openings may decline because openings become filled, or because previous openings are removed without filling positions.

The Unemployment Level is the aggregate measure of people currently unemployed in the US. Someone in the labor force is defined as unemployed if they were not employed during the survey reference week, were available for work, and made at least one active effort to find a job during the 4-week survey period.

The Unemployment Level is collected in the CPS and published by the BLS. It is provided on a monthly basis, so this data is used in part by macroeconomists as an initial economic indicator of current trends. The Unemployment Level helps government agencies, financial markets, and researchers gauge the overall health of the economy.

Note that individuals that are not employed but not actively looking for a job are not counted as unemployed. For instance, declines in the Unemployment Level may either reflect movements of unemployed individuals into the labor force because they found a job, or movements of unemployed individuals out of the labor force because they stopped looking to find a job.
