Something seems amiss with the 2000 data as presented at this website.
I looked at census tracts 77 + 87, which more or less cover Spruce Hill.
The 1990 census had these tracts, together, with a population of 11,776 and a total of 6,104 housing units. The population number is well below the 16,000 cited by the Spruce Hill Community Association, but seems at least in the ballpark because the census tract boundaries seem somewhat more restricted than SHCA's. But the 2000 figures given here are population of 9,579 and housing units of 5,255 when the screen first comes up, then population of 8,583 and housing units of 4,679 when you ask for a display "without bar graphs."
The 1990 --> 2000 discrepancy doesn't make sense considering the census tract boundaries don't "seem" to have changed. And the with --> without bar graph differences are a real mystery.
Perhaps you can get Dr Wong to look into this.
