The subject matter of human geography continues to grow over the period. It has widened its scope considerably. In the early 20th century, several new branches emerged out of it such as population geography, political geography, agricultural geography, etc. Its aim was to study emerging issues and problems like political dimensions and social relevance. In doing so, human geography has not only become more integrative and interdisciplinary in nature but has also incorporated several new approaches into its field. It gives the necessary spatial and systematic view point to the other social sciences which they otherwise lack. At the same time, human geography draws on other sciences, the analysis and identifies with its sub-fields such as political, economic and social geography.
