The most important factor determining social mobility in Finland was education. Children who attained a higher level of education than their parents were often able to rise in the hierarchy of occupations. A tripling or quadrupling in any one generation of the numbers receiving schooling beyond the required minimum reflected the needs of a developing economy for skilled employees. Obtaining advanced training or education was easier for some than for others, however, and the children of white-collar employees still were more likely to become white-collar employees themselves than were the children of farmers and blue-collar workers. In addition, children of white-collar professionals were more likely than not to remain in that class.
