Your topic is relatively standard, mainly depending on what major you study or what direction you want to investigate. For example, when I was at school, I studied economics. When you go home in summer vacation or winter vacation, you can investigate your hometown, and the topics are "price level survey in xx county" and "consumption level survey of residents in xx county".

Moreover, before doing this research, you must consider what the purpose of your report is and what method you intend to use (questionnaire or interview, or search for information on the Internet). If it is a questionnaire survey, you should also design a questionnaire, and consider how many questionnaires can reflect the facts. After the collection, you should sort out the questionnaire and summarize it by category.

After summing up, it is the research report.

First, indicate the purpose, time, method, area and sample size of the survey.

Then explain: the findings and conclusions.

Then explain: investigate the specific situation. Explain the answers to each question one by one in the order of the questionnaire.

Basically, this is the end of a report, but if you can, you can also add a problem analysis and solution suggestion.

That's what I used to do. (I won the first prize for reporting unexpectedly, hehe) I hope it will help you.
