“…For instance, Italy and Turkey showed a particularly low share (5% and 4%, respectively); from the opposite side of the ranking, particularly high shares were observed in Israel (43%), Canada (42%), and New Zealand (42%). Low upward mobility, however, does not necessarily indicate a lower opportunity to attain a high education level [15]; upward mobility may be low in countries where a considerable share of parents has already attained tertiary education [16][17][18][19]. To evaluate how a family's educational level matters for a given individual in achieving the highest educational title, 26 countries (Australia, Austria, Canada, Chile, Denmark, Estonia, Finland, France, Germany, Japan, Greece, Ireland, Israel, Italy, Korea, Norway, New Zealand, Holland, Poland, Czech Republic, Slovakia, Slovenia, Spain, United States, Sweden, and Turkey) were investigated considering aggregate (country-level) data for individuals 30-44 years old from OECD [14].…”
