This paper investigates occupational segregation by gender in the Finnish private sector during the period 1995-2004 using Statistics Finlands Structure of Earnings data. The results show that although the occupational differences between genders have decreased during the investigation period occupational segregation by gender is still high in the Finnish labour market. The level of segregation is also found to vary by background characteristics. For example, segregation is higher among older workers. Moreover, segregation seems to decrease with the level of education : segregation is clearly lower among university graduates compared to workers with lower education. There is variation in the level of segregation also by the type of industry. Segregation is much higher in the male-dominated industries than in the female-dominated or in the gender-balanced industries. The paper also utilizes the panel structure of the data to investigate the question of how occupational differences between men and women evolve with work experience. The results suggest that there are only small changes in the level of occupational segregation along the working career.
