Calculating average number of residents per household

Question

I have a shape file (Polygon) of a district, and a shape file (Point) of residents per household by address. I wish to determine the average number of residents per household in a district. I already have a layer for each district with it's addresses.

I am looking to do the following equation {RESIDENT_COUNT_TOTAL] / [TOTAL_NUMBER_FULLADDR] = Avg Residents per household.

Can someone help me with this process?

I already have a layer for each district with it's addresses.

Do you mean you have a point feature class, one for each address, and a column containing the district identifier? If not, intersect the district layer with the address layer to get this feature class.

Then use Summary Statistics to calculate the mean (case = district field, statistic = mean on residents per household field).
