Dummies created from the dependent variable, which is described in more detail above, show that
43 % of the sample population are employed. 4.5 % are unemployed and the remaining 52.5 % are
outside the labour market. Disregarding the non-users of antidepressants, it turns out that only 26.3
% of the antidepressant users are employed, whereas 7.1 % of them are unemployed and 66.6 %
outside the labour market. On average the sample population is 50 years old, and almost 70 % of
them are concentrated between the ages of 46 and 64. The group of antidepressant users is on
average about a year older than the non-users of antidepressants. The average use of MTX is 189
defined daily dosages (DDD) per year, but there is a very large standard deviation of 106, because
the dosages range from 30 to 1200 DDD per year. Roughly 40 % of the patients use up to 100 DDD
of MTX per year. Most of the intake of MTX is concentrated at dosages up to 300 DDD, since only
about 8 % use above 300 DDD per year. The average DDD of MTX per year is about 7 DDD lower
for antidepressant users than for non-users. 10 % of the sample population use antidepressants. For
the 10 % of the sample that use antidepressants, the average dose is 272 defined daily dosages
(DDD). With a standard deviation of 268, the variance of the antidepressant use is even greater than
the variance of the MTX use. For the antidepressant users the defined daily dosages per year range
from 5 – 1790. The largest group of 34.6 % is placed in the lowest category of up to a 100 DDD per
year. 17.1 % of the antidepressant users take between 100 and 200 DDD per year and 14.6 % take
between 200 and 300 DDD per year. Finally, only 33.7 % take more than 300 DDD antidepressants
per year. For the whole sample population the total taxable wage income stated in the tax
information sheet is 88,835 kr per year on average. Again the variance is substantial due to the fact
that the maximum pay is 1,379,430 kr, while at the same time 54.6 % have a wage income of zero.
Since about 70 % of the population is between the age 46 and 64, it is natural that the percentages
of people, who have children in the ages 0-14, are low. Looking at country of origin, 96.1 % are
from Denmark, Greenland and the Faroe Islands, while 2.3 % come from more developed countries,
defined as Europe, North America, Japan, New Zealand and Australia. <strong>An</strong>d the remaining 1.6 %
come from less developed countries, which consist of all countries not included in the first two
categories.
