What I need: n_radio_stations needs to be normalized by the area of the state (area_km2) to give the number of radio stations per square miles. Then this variable needs to be normalized by each state’s population (i_pop_total) to give the number of radio stations per unit of area per population.
This variable will provide an index of the intensity of the radio infrastructure in each state. I’m confused about how to do this calculation. Can someone help?
The aforementioned data follows below.
ibge_uf_code = state’s ID
