The charts provide an analysis of the weight issues among the residents of the town of Charlestown in 1955 and in 2015.

In 1955, the youngest age group had the fewest number of weight issues, with more than 70% of 20-29-year-olds being assessed as having a healthy weight. In the same year, excess weight was only a significant problem among 40-49-year-olds, 20-30% of whom were classified as either overweight or obese. In fact, being underweight was a more significant problem affecting more than twenty percent of each age group, and the elderly in particular, with 40% of the over 60s being classified as underweight.

In stark contrast to this, in 2015, being underweight was only a problem among 20-29-year olds, with 20% obtaining this diagnosis, and the number of underweight elderly people had fallen by 10%. The charts clearly show that, in modern times, obesity poses a considerable problem from the age of 30 upwards. In fact, there was a steadily increase in this problem in almost every age group over 29 until the age of 60, when the vast majority are considered to have an unhealthy weight. It is important to note that, by the age of 60, less than 50% of each age group was considered to have a perfect weight by the year 2015. This is a fall in10% compared to the same age group in 1955.

Comparing the two years, it is clear that there has been a significant increase in the number of obese people in Charlestown, and there was a general drop in the number of underweight people between 1955 and 2015.

图表对1955年和2015年查尔斯镇居民的体重问题进行了分析。

1955年，最年轻的年龄段的体重问题最少，20-29岁的人中，超过70%的人被评估为体重健康。同年，体重超标只是40-49岁人群中的一个重要问题，其中20-30%的人被归为超重或肥胖。事实上，体重不足是一个更严重的问题，影响着每个年龄组中超过20%的人，尤其是老年人，其中40%的60岁以上的人被归类为体重不足。

与此形成鲜明对比的是，在2015年，体重不足只是20-29岁人群的问题，有20%的人获得了这一诊断，而体重不足的老人数量下降了10%。这些图表清楚地表明，在现代社会，从30岁起，肥胖就构成了一个相当大的问题。事实上，在29岁以上，几乎每个年龄段的人都存在这个问题，一直到60岁，绝大多数人都被认为是体重不健康。值得注意的是，到了60岁，到2015年，每个年龄段被认为拥有完美体重的人不到50%。这与1955年同一年龄组相比，下降了10%。

对比这两年的情况，可以看出，在1955年到2015年期间，查尔斯顿的肥胖人数明显增加，而体重不足的人数普遍下降。
