Compare the two charts below. We can see that more male users than female users .Male users account for 56% and female users account for 44% in 2017. While in 2019,male users increase 0.5%,and that means female users are decline.The statistics are beyond my exception, for I thought that women are more commonly use the social media than men.If we distinguish by the age,here I compare 18-24 with 35-44 ,In 2017,there 30% of young people use facebook and 15% of elder use facebook.Then in 2019,young people decline 5%,and the elder increase 1.5%.That means 360 million people,is not a minority. In short,we can find that fewer and fewer young people use facebook,more and more elders use facebook.
