Looking For Annual Datasets Of Any Kind For African Cities

Hi guys,

I am writing a paper on the changes in vulnerability of african cities and I’ve had a problem with finding data. I am looking for indicators that are annual (at least 30 years back) of any kind, although economic or environmental ones are more needed. While it is not difficult to find such data for african countries, african cities are borderline impossible. The only resource I found was Global Data Lab which is kind of the perfect example of what I am looking for:

Again, any data in this form is appreciated though I’m aware how hard it is to find.
