Generally speaking, you need to provide stata the weights by yourself.

If each observation in the sample is average data for each census
tract - you need to correct for hetheroskedasticity by multiplying
each observation in the square root of the population size for each
census tract.

If each of your observation is not average but rather refers to
specific properties - you can generate regional dummy variables and
run -heckman-

Finally, if your data is panel - you can use the -xtreg- command and
run a fixed-effect model, which is also based on regional dummies

I have data on 24000 observations of property prices, the parcel number, lat  and long associated , census tract numbers, structural attributes, location attributes. It it possible to make a spatial weight matrix in stata for my dataset???
