Summary of Data Updates

Performance measures have different time intervals of data updates. The schedule of data updates provides a summary of when the performance measure was last updated and when is the next anticipated update. In the table below, the "last update" column corresponds to when the performance measure data point was last updated on this website - not when the data was collected or released by its source. Similarly, the "next data update" is an estimate of when the performance measures data will be updated - not when the source data will be released or collected. The next data update date may be subject to change.
