By the 19th century, timber and other resources were being exported to India. Industrialization based on agricultural products such as jute began in the 1930's and infrastructure such roadways, railways and electricity were extended across the border before it reached Nepal's hill regions.The Outer Terai is culturally more similar to adjacent parts of India's Bihar and Uttar Pradesh than to the hill region of Nepal.
