# Information Schema TABLE\_STATISTICS Table

The [Information Schema](/docs/server/reference/system-tables/information-schema.md) `TABLE_STATISTICS` table shows statistics on table usage.

This is part of the [User Statistics](/docs/server/ha-and-performance/optimization-and-tuning/query-optimizations/statistics-for-optimizing-queries/user-statistics.md) feature, which is not enabled by default.

It contains the following columns:
