Hey there I'm Algerian. I find height to be an interesting topic in Algeria because a lot of people grew much taller after france left algeria, so i think environment and nutrition are big factors. My mom, her sister, and her brother were all born in the early 50s during the war and french rule and they were all relatively short. 5'0 5'2 and 5'7 for my uncle, while her other two siblings a sister and brother who were born after the war were much taller. My aunt was 5'6 and my uncle 6'0, and now his son is 6'5.
