The line chart illustrates the percentage of several cohorts of European citizens who visited the gym from 1990 to 2010.
Large shares of younger demographics went to gym in the depicted period. First, less than 10% of young adults aged 18 to 24 years-old exercised in gyms in 1990. This number increased over the years, reaching 20% around 1995, and 30% by 1998. Next, it peaked around 2006, when almost 60% of 18-24 years-old were going to the gym. After that, it dropped to nearly 50% around 2008, before increasing again until 2010. Second, around 10% of individuals aged 25-34 visited the gym in 1990. This figure rose sharply, reaching 30% around 1999, when it was surpassed by those 18-24 years-old. Following, about half of those adults aged 25-34 were going to the gym by 2010.
Older citizens did not go to the gym as often as younger populations. To begin, less than 5% of adults aged 35-44 went to the gym in 1990. While 10% of this cohort went to the gym in 1998, only in 2002 it reached 20% of the population this age. Subsequently, after 2006 there was a sharp rise in the share of people aged 35-44 going to the gym, reaching 40% of the population by 2010. Lastly, regarding individuals over 45 years-old, their numbers in 1990 were almost 0%. In 2002, 10% of this cohort was going to the gym and it was in 2010 that this figure reached 20%.
In summary, younger populations had larger share of the population going to the gym and less people aged over 35 years-old went to the gym.
