I jumped straight into population numbers without pausing to define what 'need' even means, which felt sloppy in retrospect.
Clarify the scope by defining the city's population and assuming a standard grocery store size and shopping frequency. Then estimate demand based on household grocery needs and supply based on store capacity, and reconcile the two to determine the number of stores needed.
Pro tip: Acknowledge that grocery stores vary in size and format (e.g., supermarkets, convenience stores) and that competition and geography affect distribution; state your assumptions clearly and offer to adjust if needed.
Ask clarifying questions to define the city's population, average household size, and what constitutes a 'grocery store' (e.g., full-service supermarket). State any assumptions you make.
Calculate total weekly grocery spending or volume by multiplying the number of households by average weekly grocery needs. This represents the total demand the city must satisfy.
Determine the average capacity of a grocery store in terms of revenue or customers served per week, based on typical store size and throughput.
Divide total demand by the capacity per store to get a baseline number. Adjust for factors like competition, geography, and shopping preferences.
Compare your estimate to known benchmarks (e.g., stores per capita in similar cities) and discuss potential variations due to income levels, car ownership, and online grocery penetration.
