population functions: the code seems really thorough with conditions for different sex; however, it seems like there is a lot of repetition in the code because of different conditions. I would suggest defining the male index, female index and then updating start_indx and end_index depending on those conditions rather than writing it out every time.
population_df function: the deliverables instruction told us to index it by year and country but it seems like there can be only one country can be entered for the function.
population pyramid/animated population pyramid: I really liked looking at the animated population pyramid! I think you can definitely improve the code by making it into a function and setting country as a parameter so that you can visualize them in other countries easily as well!
Project related codes (population growth and agricultural production):
I really enjoyed looking at these; it was interesting to see the correlation between agricultural production and population growth.
For the population growth rates in India by Urban and Rural Area 1960-2020 graph, I think it might be better for the plots to be of different color so that there is a disparity between rural, urban and total population growth.
