Please review my writing task 1

The bar chart shows the information of multiple social networking sites used by people who live in Canada in 2014 and 2015.

Overall, in both 2014 and 2015, the majority of the Canadian population used only one social networking site, while there were very few people who used four to five sites. In 2014, the percentage of people using one site was highest, at 36. There was not much difference in the percentage of people using two sites and people who did not use any social network, around 22 and 23. People using three sites only took 12%,  and the percentage of persons using four to five sites was nowhere near as high as three sites, only 5% and 2%.

The percentage of multiple social network users in 2015 had similar trends to 2014. People using one site still had the highest percentage, 28%. Leading right after were the percentages of people who did not have any social network and users who had two to three sites, 21, 23 and 12. Last came the four to five-site users' percentage, only 8% and 4%.
