ABSTRACT
Purpose:
to assess the expressive and receptive vocabulary of preschool children and trace the relationship with different socioeconomic factors.
Methods:

For statistical analyses, the non-parametric Kruskal-Wallis test, Bonferroni post hoc corrections to check significant differences and Spearman correlation were used.
Results:
the results found showed a statistically significant relationship between factors such as salary range, mother's and father's education and performance on tests of receptive and expressive vocabulary and mental maturity.
Conclusion:
evidence showed the relationship of socioeconomic factors with language development in preschoolers.
