Aggregated statistics on an area, such a median age, average household size, income and so on are available through the Census Bureau. You won't and shouldn't be able to find individual information on a person without their permission.
You can get basic demographics on this website http://www.SumnerRealty.com/content/listdetail.html?propid=130230802&proptype= &zipcode=75216&search_by=zipcode by clicking on the Demographics tab.
Names and addresses of owners are available through tax records.
I am not sure why you want such information, but good luck.
