This data is not audited, and has not been reviewed, approved, or otherwise checked in any way by NAPHA. It is provided for informational purposes only.
Data set is all registered NAPHA horses (online studbook registration number > 1000) with a recorded foal date and with a dam with a recorded foal date. Total horses found that met this criteria were 16815. Age is based on actual time elapsed from birth of dam to birth of foal, as opposed to show rules based on Jan. 1.
N = 16815
Data analysis performed by Stevi Deter on 11-Oct-2005. Feel free to contact me directly with any questions.
Unless otherwise noted, the data source is all horses with a record in the NAPHA online studbook (http://www.pphrnastudbook.com/). Data set includes up to 9/15/2005 update to online studbook.
Horses in the online studbook with registration numbers below 1000 are not registered with NAPHA, but are included as parents of registered horses. Unless otherwise noted, statistics include these reference horses. "Registered horse" data set refers only to those horses with registration numbers above 1000. "All horses" includes reference horses (all horses with a record in the online studbook).
