The image exhibits a line graph titled 'Obesity Rate (by age)' with years on the x-axis ranging from 1971 to 2005 and percent on the y-axis from 0 to 45. There are four labeled trend lines: 18-29, 30-44, 45-64, and 65-74. The 18-29 age group starts at approximately 5% in 1971, gradually increasing to 15% in 1988, then to 17.5% in 1999, and reaching just over 17.5% in 2005. The 30-44 age group begins around 12.5% in 1971, escalating to 25% in 1988, surging to just below 35% in 1999, and peaking around 37.5% in 2005. The 45-64 segment initiates at just below 15% in 1971, climbing to just below 30% in 1988, soaring to approximately 37.5% in 1999, and attaining nearly 40% in 2005. Lastly, the 65-74 cohort commences at roughly 12.5% in 1971, advances to just below 20% in 1988, amplifies to just over 20% in 1999, and culminates at 22.5% in 2005.

The line graph illustrates the percentage of individuals who were obese and divided according to their age groups in one country between 7 years, starting from 1971.
Overall, all age groups rose similarly in obesity proportions over the period, with the group aged 45-64 maintaining its significant dominance and the group aged 18-29 still in the least categories.
Regarding the 45- to 64-year-old and the 65- to 74-year-old groups, which started the period at the same percentage at around 17%, and they rose similarly and dramatically throughout the period, overtaking each other. The latter, however, remained unchanged in the last year. Unlike such performance of the latter, the former did not stop rising and ended up demonstrating the highest age group in terms of being obese.
As for the youngest age groups, even though both started the period at different proportions, they showed a similar trend. The 18- to 29-year-old saw a massive growth over the period by reaching almost 25% from about 7%, and the 30- to 44-year-old group witnessed a rapid increase in the whole period, constituting around 35% from the lowest position.
