Sex and the City

Throughout the industrialized world, young women outnumber young men in urban areas. This paper proposes that such a pattern may be linked to higher male incomes in urban areas. The argument is that urban areas offer skilled workers better labor markets. Assuming that there are more skilled males than females, this alone would predict a surplus of males. However, the presence of males with high incomes may attract not only skilled females but also unskilled females. Thus, a surplus of women in urban areas may result from a combination of better labor and marriage markets. Swedish municipality data support the results.
