For
the same reasons mentioned in the preceding section (especially in
relation to the rate of occupancy), it can be noted that the indicators
of education are low in the case of extended households, and nucleus
households with relatives, compared with nucleus households. Also,
informal subsistence households (the category "other" in the
questionnaire) rank lowest with respect to the indicators of education,
as these households include an important proportion of old people, women
and widows.
On the other hand, the number of cars owned by the household seems to be
strongly correlated with the education index, as 53.1 percent of all
households that are classified below the threshold do not own a car; the
percentage falling with the increase in the number of cars owned. This
is explained by the car being an indirect indicator of the level of
income and is reflected in the sharp drop in the proportion of
households below the threshold, from 53.1 percent of households which do
not own a car to 23.2 percent for those that own one car. This, in turn,
reflects the bearing of the means of transport, and the time spent in
commuting to and from school, on the level of scholastic achievement.
These observations are confirmed by the study referred to above, which
shows that the lowest level of achievement is recorded among students
that commute to school walking, and those who spend a longer time to
reach school.
