I have to say it's hard to believe Miami's weighted density would be so close to the gross/overall density. Did your total population add up to 399,000? What was your methodology?

There's basically two ways of calculating the weighted density that I can think of.

1. Take the population of each census tract and divide by the population of the city. Multiply this number by the census tract's density to get the "weight". Do this for all the city's census tracts and add up all the "weights".

2. Take the population of each census tract and multiply by the density to get the "weight". Add up all the weights and divide the sum of all the weights by Miami's total population.
