The table presents data on the number of participants in a wildlife survey conducted in Britain from 2001 to 2009. Overall, there was a significant increase in the total number of British adults and children participating from 2001 to 2009. The year with the highest level of adult participation was 2005, while 2009 saw the highest number of child participants.
Between 2001 and 2003, the initial year recorded the smallest number of survey takers with 36.000 adults and 12.000 children. Two years later, the total number of people doing the survey remarkably increased to 248.000, which was 200.000 higher than the initial year. In 2003, besides the upsurge of adult takers to 212.000, the figure for children tripled to 36.000 children.
Regarding the last three years, the wildlife survey appealed to more adult participation with 331.000 out of 362.000 in total people in 2007, as opposed to a drop to 31.000 children in the same year. 2009 recorded the highest total number of survey participants, at 540.000 participants, indicating a sudden drop in adult participation as well as a surge in children’s engagement to reach an equal figure of 270.000 individuals.
