The graph gives information about male and female gym membership between 1980 and 2010.

Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The line graph illustrates the number of men and women registering for a gym membership. The vertical axis represents units of one thousand. The horizontal axis indicates 5-year time spans. The data is shown between 1980 and 2010.

Overall, the number of males was significantly higher than that of females over time. While the number of men wildly fluctuated and eventually dropped, there was an upward trend in women as regular gym-goers throughout the years.

In 1980, the number of men increased dramatically, at nearly 2100 doubling that of women, only at exactly 1000. Between 1985 and 1995, there was a considerable drop in male membership, ranging from 4000 to modestly 1800. Conversely, the value for women gradually fluctuated, went up, and finally peaked at more or less 3000 in 1995.

In the late nineties and the early twenties, the figure of men showed a rough fluctuation once again, peaking at 5000 in 2005, but drastically went down at the end of the period, at fewer 700 in 2010 as opposed to approximately 2000 female memberships. Additionally, the data for women marginally fell but reached a summit twice recorded in 1995 and 2005, at the same value of 3000.
