So I was wondering how many realtors there are per person in Marin County.
I asked
these people if they would tell me for free how many realtors there are in Marin and they kindly did so; there are 1,677 realtors in Marin as of today.
According to the U.S. Census Bureau data, in 2005 Marin's total population was about 246,960 people. The U.S. Census Bureau says that in the year 2000 20.3% of the county's total population was 18 years of age or younger. So assuming that percentage was the same in 2005 as it was in 2000, that puts Marin's total adult population in 2005 at roughly 196,827 bodies (and one arm in change).
That means in 2005 there was about one realtor per 117 adults in Marin.
If we assume that all of those adults are "coupled" to a Marin adult resident (e.g., married, living with, whatever -- basically, buying a house as a couple), then there is one realtor for every 59 adult couples in Marin.
What does it mean? Nothing. It is a useless factoid.
Update: The Marin Assessor's office says that a total of 4,304 SFR sales occurred in Marin in 2005. So that would be one realtor per 2.6 SFR sales. Again, meaningless.
