In the early twentieth century, Selden was largely rural. It is only in the late twentieth century that the town began to see growth. In 1931, real estate agents began marketing small lots to New Yorkers as a retreat from city life. The city's rural character began to change and small lots with large homes were added. This change fueled suburban development, which began in earnest in the early 1950s.
