In-District Penetration Rate

The penetration rate is calculated by dividing the unduplicated COCC IN-DISTRICT headcount for a given academic year by the Tri-County Population Estimate determined for the lead year (Ex. IN-DISTRICT HC for 2001-02 is divided by Tri-County Population Estimate from July 1, 2001). Students Aged 18 and up are included in the analysis.
