buffer base on value of census not distance

[SamanthaOsborne]

need to make a buffer base on getting 10,000 households.  I have the household data from census blocks. Need to Create a buffer from center of town and generate a buffer to reach 10,000 households. Know for each city it will be different radius. Is there a way to have a buffer generate?

That would require iterating a buffer from each city centre, performing a selection on the household data until your threshold number is reached.  There is no built in tool, it would need to be written.

To complicate things, what type of buffer do you want? a simple Euclidean distance buffer? a buffer based on road distance?
