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.
