3.1 Relationship between household income and education level of
household head
A simple regression model used to reflect the relationship between income
and education; it was positive which means when the education level of
household head move from one category to the next (from uncompleted
secondary education to completed secondary education) then household
income increases. The same result appears when multiple regression used by
adding other variables.

All independent variables in income model are statistically significant
relationship with dependent variable log (income) expect age of HH and all
interaction between independent variables are statistically significant.
- B represents the difference in the predicted value of log income of HH for
i
each one-unit difference in X , if the rest of independent variables remain
i
constant.
- B = 0.138067 represents the increase in log income value When education
1
level of HH changes from uncompleted secondary to completed secondary, if
the rest of independent variables are constant, the same positive relation of
simple regression. And it reflects the most effective variable on income in this
model that reflect the strong relationship between income and education.

3.2 Relationship between individuals’ education level and household
income
How does income of household influence on completed education of
individual?
An indicator variable created “Educst” to express education level of individuals
because secondary education in Egypt is considered to be the good or enough
level required to have a good quality education where value 1 indicate that
