Here's how to do it yourself, no measuring tape required: If you want to find the population density of any block in Davis, just use the Census website. Following the instructions below will take you to a map of Davis with population density sorted Block by Block. Above the map you can set the action ("re-center and zoom" by default) to "Identify". This will bring up a little pop-up window with the population density of the block you click on. Sample results: Old North: between D & E Street and 6th & 7th Street: 5000 persons per square mile College Park: west side of College Park drive: 5261 persons per square mile College Park: east side of College Park drive: 4138 persons per square mile Aggie Village: 4714 persons per square mile Instructions: 1. For the map of population density by Census Blocks for Davis: a. Go to http://www.census.gov b. Click on ?Your Gateway to Census 2000? c. Click on ?American FactFinder? d. Click on ?Expert User?

For small areas, this can lead to serious underrepresentation of density. The specifics of this are given in my memo. Therefore, Z, in my view you are incorrect about the need for measurement. For small areas, measurement might be needed to get the proper precision.
