The table presents the number of women and men from 2005 to 2009 that answered a national health survey about their sleeping habits.
Overall, it is clear that as the years went by, more and more people took part in the health survey about sleep. However, there seems to be no trend for why the gender distribution of participants was not always equal.
In 2005, only 8000 people participated in the national health survey about sleeping habits. Three-fourths of the respondents were women, while only one-fourth or 2000 were men. A year later, the figures grew sixfold as 48,000 people answered the survey. But this time the majority of the participants were men (36,000), while only 12,000 women got involved. However, the following year, the distribution of participating men and women was equal, as 32,000 of each gender answered the questions.
The final two years showed a tremendous increase as the overall figures swelled in 2008 and 2009 to 362,000 and 540,000 respondents, respectively. In 2008, of the 362,000 people that answered the national health survey, roughly 91% or 331,000 participants were women, while just 9% or 31,000 were men. But in 2009, when the numbers grew to more than half a million, the figures for both men and women were the same at 270,000 respondents each.
