Years of empirical research show that Internet use is far more common in cities than in rural areas and this continues to be true in Azerbaijan.
As of June 2018, 32% of the total population of Azerbaijan is on Facebook, 30% of the 14+ age population. That’s 44% of men and 21% of women.
60% of 15-24 year olds are on Facebook, 78% of men and 41% of women.
But, in looking at geography, 81% of all Facebook users in Azerbaijan are within 25 miles (~40 km) of the capital, Baku and if one only looks at women, 87% of female Facebook users in Azerbaijan are within 25 miles of Baku.
