Meta Analyses
The analyses in this section relate to the database itself, providing information as to the quantity and quality of the information contained in the ADR database. Because of discontinuities in data collection, one should not interpret analyses presented in this section as reflecting the details of year-to-year changes in distance running world-wide but rather reflect general trends. Certainly the numbers of performances qualifying for inclusion in the ADR database has grown since the 1970's, however the factor is not as large as might be inferred from these analyses since coverage has tended to improve in recent years.

Notes: The count of performances and races includes grand prix standings
and stage races. The runners qualified by time represent those that have achieved at least one of the ARRS time
standards. Other runners include marathon winners, veterans under the qualifying
standards for their age group, and runners who have won a single prize purse of US$1000
or more, that are not otherwise qualified by time.
