I am looking for an explanation and the answers to this homework assignment

Obtain data on the number of males and females in the year 2020 (these are the classifications provided by the Census Bureau) in five-year categories for the City of Detroit using ACS 5-year estimates in Table S0101. Perform a cohort component population projection to the year 2025. Use the model provided in the example we did in class but bear in mind that this is just one way to perform these projections. Furthermore, use the survival, births, and migration rate as in the example but again bear in mind that these have changed since the data in the example was collected and we are assuming that males and females have the same survival, birth, and migration rates, which 1s not the case; we are using these same rates to avoid having to go hunt for more current data
