Estimation shows that worker education is found to be significant in the demand for unskilled immigrants. Estimates suggest a 10% increase in the proportion of workers who have less than 6 grade of education (some elementary) would raise the probability of a firm employing unskilled migrants by 0.9% or increase about 3.6–3.8% of the unskilled migrant share.
