There are a few possible reasons for why your Google account might think you're from Africa:
-It could be based on your IP address. If you're accessing your account from an African country or region, Google may assume that you're from there.
-It could also be based on your account activity. If you've been searching for and clicking on content related to Africa, Google may think that you're interested in that region.
-There may also be some data in your account settings that indicate you're from Africa. For example, if your account settings list your current location as being in Africa, or if you have previously listed your location as being in Africa, Google may think you're from there.
If you're not from Africa and you don't want your account to think you are, there are a few things you can do:
-Change your location settings in your account.
-Make sure you're not accessing your account from an IP address in an African country or region.
-Search for and click on content from other regions to help give Google a better idea of your interests.
