Who Says There are Too Many Smith?

How many Smith's are there, in the universe?

In the Washington County phone book, there are 1303 phone numbers listed under the last name of Smith.
My family is only one of those numbers.

On April 1st, 2000 Oregon's census reported 3,421,399 people in the state, with 445,342 in Washington County.
At 2.5 people per phone number, that assumes 0.73%, or 1 one out of every 136 people in Washington County Oregon is a Smith.

Is that too many?

Below is a chart showing the concentration of Smiths in the US in 1990.  Interesting that Oregon had the lowest concentration in the US.
