The bar graph shows the percentage of the people who donate their money to charities with the age range over the 20-year period from 1990 to 2010.
Overall, it is evident that 36-50 aged individuals recorded the highest proportion in both given years. In contrast young people (18-25 age range) showed the smallest figures in this timeframe.
A closer examination of data reveals that in 1990, people aged 35-50 led with the highest share, reporting just above 40% in terms of giving money to foundations, followed closely by the elderly category (51-65), which accounted for roughly 35%. The figure for people between 26 and 35 age and people who are older than 65 years old had comparable percentage points with above 30% each. However, the 18-25 aged people made up the smallest share, which represented at just above 15%.
In 2010, the group of the 51-65 aged people became dominant, standing at nearly 40%. Meanwhile the proportions of 35-50 along with 65 and over aged people shared the similar number, which comprised 35% each. As for the remaining two groups, both saw a modest decline at just below 25% and around 6% respectively.
