Gallup's Job Creation Index is based on employed Americans' estimates of their companies' hiring and firing practices. Gallup asks its sample of employed Americans each day whether their companies are hiring new people and expanding the size of their workforces, not changing the size of their workforces, or letting people go and reducing the size of their workforces. The resulting index -- computed on a daily and a weekly basis by subtracting the percentage of employers letting people go from the percentage hiring -- is a real-time indicator of the nation's employment picture across all industry and business sectors. Gallup analysis indicates that the Job Creation Index is an excellent predictor of weekly jobless claims that the U.S. Labor Department reports each Thursday. The index may also pick up hiring trends days or weeks before they are manifested in the official unemployment rate or other lagging indicators. Finally, the index measures job creation (hiring) and job loss (letting go) on a continuous basis. This provides additional real-time insight not available from broadly aggregated indicators and unemployment data.
