The given table compares the number of participants in two different age groups in a marathon between 2008 and 2012.
Overall, the total number of runners participating in the marathon experienced an upward trend over the time frame. Notably, while both surveyed age groups increased consistently, young adults witnessed a more substantial growth in their number of participants.
A closer look at the table reveals that the marathon saw a dramatic increase in its number of participants. In 2008, there were about 2000 participants, and the figure climbed by 200 more participants each year until 2010. By 2012, the number of participants peaked at 2800.
Examining closer at the two surveyed age groups, the 18-39 age group experienced a more substantial growth in number of participants than its 40+ counterparts. Initially, young adult participants outnumbered the middle-aged, at 1200 and 800 respectively. The figure for both age groups then increased consistently over the time frame. By 2012, the number of participants aged 18-39 increased by 550, reaching 1750, the largest contributor to the total number of participants. Meanwhile, the figure for people aged 40+ rose to 1050, which was 700 fewer than that of the 18-39 age group.
