How to write the methodology of my Eco extended essay about "externalities of production"?

I'm working on the aeronautical industry (airbus) and the airport place next to its main site.

I have to use microecononics, macroeconomics and international economics to talk about the advantages and the drawbacks of the arrival of this industry on the city.

I intend to use a questionnaire to get primary data. Could you suggest relevant questions to be submitted to inhabitants of the city?
