This is a very interesting bar graph, it represents the population structure in New York. The x axis of the the graph represents the population number in thousands and the y axis shows the age rang starting from 0 to 80+. For each age group there is a four year gap in the ages. Both graphs besides each other makes a comparison between the male and female gender and their ages. From studying the graph it is evident that both male and female highest population is around 480 at ages 40-44. Whereas the lowest population is in the age group of 80+. I chose this graph because it is very clear on the information it is representing and also it allows us to make comparison.
Reference? How was graph used in its original context?
