Question

What is a report on the demographic structure of your neighbourhood?

Answer 1

In order to develop a report on the demographic structure, you need to carry out a survey with the local people

This is not as hard as most people think. You need to develop a simple sampling sheet with colums such as name, age, sex, occupation, income etc.
Most people will be happy to talk to you and e.g. in a locality of 5,000 people, such a survey can be completed within 10-14 days
