Baichung is a senior market research analyst in BRIM, a top market research firm. BRIM has been approached by the local municipal authorities to investigate a typical urban problem in a certain locality of metro city. The authorities have noticed that the citizens are not shopping from the stores in that area. Consequently, the shops are closing making the neighbourhoods run-down and unsafe. Baichung has been given the responsibility to handle this project on behalf of BRIM. What is the broad research question and what can be the possible sub-questions that Baichung needs to identify, before starting to work on them?
