Socio-Demographic Variables and Their Influence on English Grammar Proficiency: A Literature Review

Abstract

This literature review examines the influence of selected socio-demographic variables on English grammar proficiency among students, with particular emphasis on the Philippine educational context. The review focuses on age, gender, first language spoken at home, socio-economic status, and parental educational attainment as key determinants of grammatical development. Anchored on theories from second language acquisition, sociolinguistics, and educational psychology, the study synthesizes findings from peer-reviewed journal articles, academic books, and reputable scholarly sources to explain how cognitive, linguistic, and environmental mechanisms interact to shape grammar learning outcomes. The analysis reveals that younger learners tend to acquire grammatical structures more intuitively due to greater neural plasticity, while older learners benefit from metacognitive strategies and formal instruction. Gender-related differences in motivation and learning strategies often result in higher grammar performance among female learners. Linguistic transfer from the first language significantly affects English grammar acquisition, particularly in multilingual contexts such as the Philippines. Moreover, access to educational resources and supportive home literacy environments, which are strongly associated with socio-economic status and parental education, play a crucial role in grammar proficiency development. The review underscores the importance of integrating socio-demographic considerations into language instruction, curriculum design, and educational policy to promote equitable and effective grammar learning.
