Hey there! I'm happy to help!
First of all, this building would attract small, wealthy families.
A large family would not do well in an apartment, but a smaller one would fit and it would be more <u>economically advantageous</u> as you would not have to pay for as many things for your kids. These things are also more likely to expensive near a downtown business, so a smaller family would definitely be a better fit. However, a family would still need to be remotely wealthy to afford an apartment like this.
It would also be a family because if it were just a single person or a couple, a school would not be as much of a <u>pull facto</u>r.
A wealthy family is more likely to live in the suburbs of a larger city or in a more expensive house. Just with this information, you can utilize the concept of <u>distance decay</u>, which means that people are likely to interact with things closer to them. People will be more engaged with an advertisement if they are driving by it every day. So, you could put billboards or advertisement signs in the wealthy suburbs of a city or near expensive neighborhoods.
However, in a developing world comes <u>space-time compression</u>, which has diminished the effects of distance decay. This comes from technology and the Internet, which allow people to more connected than ever before. Richer families are more likely to own devices like computers and smart phones, so utilizing digital advertisements will be very effective and will probably be even more effective than physical advertisements as more wealthy families are more likely to be interacting with the Internet than poorer people.
Have a wonderful day and keep on learning! :D
