The Chatham Shagbark

We're closer to calculating our own student generation rates (SGRs). And we're using 2000 Chatham County Census data. But, we need to further partition our data, by either type of dwelling (single family, multi-family, etc.) or by number of bedrooms, to best project the number of students per proposed Briar Chapel residence. SGRs from such partitioned data should be significantly higher. Anyway, here's some numbers I cobbled together for Chatham County from the School District Demographics website:

from 2000 Census data

Year Built	Number Homes	All School Age Children	SGR	Children in Public Schools	SGR
1999 - March 2000	925	530	.573	520	.562
1995 - 1998	3005	1685	.561	1490	.496
1990 - 1994	2615	1400	.535	1180	.451
1980 - 1990	4375	1780	.407	1600	.366
1970 - 1979	3430	1045	.305	990	.289
1960 - 1969	2150	630	.293	570	.265
1950 - 1959	1900	470	.247	380	.200
1940 - 1949	1095	210	.192	180	.164
1939 - earlier	1870	445	.238	390	.209
total	23160	8200	.354	7290	.315

Even with all dwelling types lumped together, our SGRs for newer homes are 13-40% higher than Newland's 0.4.
