The line graph illustrates the percentage of obese people in a particular country over a 29-year period.
Overall, the rate of obesity increased dramatically in all age groups. The most obese people were in the 45-64 age brackets, while young adults (18-29) were comparatively more fit.
For the first five years, the percentage of people with obesity remained relatively the same across all age groups. People aged from 45 to 74 were more obese than the younger age groups; figures for both accounted for roughly 18%. From 1976 to 1999, these figures increased substantially, both reaching just over 36%. Although they both plateaued at the same level until the year 2003, only the 45-64 age group witnessed another increase to a striking 40%, which made them the most obese age group across the period.
In contrast, younger age groups (30-44 and 18-29) suffered less from obesity in the first five years, as their figures stood at 15% and well under 10% respectively. However, they both rose considerably until 1999, as did the older group, the former reaching around 21% and the latter 30%. Although there were some slight changes in the 18-29 age group, the obese percentage of them remained at 25%. Nonetheless, adults aged 30-44 demonstrated a further increase up to just under 35%, which made them the second most obese group by the end of the period.
