current levels of education attainment of the labour force, which is added to the initial/benchmark levels of 1970 taken from the population and housing census of that year. Following Loening (2005), the ensuing equations are used to construct the four levels of education attainment ( ℎ ): (2) ℎ 1," = 34 5,6 = ℎ 1,"$% ∙ 81 − 7%9 6 : + 7%9 6 ∙ (1 − "$% ) 7 6 7 6 7 6 (3) ℎ %," = 34 =,6 = ℎ %,"$% ∙ 81 − 7%9 6 : + 7%9 6 ∙ ( "$% − " ) 7 6 7 6 7 6 (4) ℎ A," = 34 B,6 = ℎ A,"$% ∙ 81 − 7%9 6 : + 7%9 6 ∙ " − 7A1 6 ∙ " 7 6 7 6 7 6 7 6 (5) ℎ D," = 34 E,6 = ℎ D,"$% ∙ 81 − 7%9 6 : + 7A1 6 ∙ " 7 6 7 6 7 6 where HNj = number of the economically active population for whom j is the highest level of schooling attained (j=0 for no school, j=1 for primary, j=2 for secondary and j=3 for higher education). PRI = enrollment ratio for primary education, SEC = enrollment ratio for secondary education, TER = enrollment ratio for tertiary education, L = number of the economically active population, L15 = number of persons aged 15, and L20 = number of persons aged 20.
