I previously made a post about the median credit score in this country.
Here is some additional info from Experian:
Based on the most current data available in the industry, the Experian National Score Index provides the most up-to-date look at U.S. consumers' credit and is a powerful indicator of the country's overall financial health. The Experian National Score Index monitors several components of consumer credit behavior to provide insight into consumer credit trends.
