Tewksbury Township’s rural setting has been preserved over the years, although slow changes have been occurring in more recent land development activities. Attempts to preserve the atmosphere and current characteristics can be seen through the passage of ordinances that require the maintenance of the historical character of buildings in the existing villages of the community. The most significant change in the community is found in the demographics of the residents and in the population growth since 1950. Historically, the land was owned predominantly by farmers. Today, much of the land is owned and populated by business executives and other professional people who commute into New York City and other metropolitan cities via the Route 78 corridor. The majority of past residential development has been single-family dwellings.
The population growth has continued from the 1950’s to the present day by increasing as follows: 1,439 residents (in 1950) to 1,908 residents (in 1960) to 2,950 residents (in 1976) to 4,300 (residents (in 1985) to 4,800 residents (in 1992), 5,500 (in 2000) and to 6,100 (in 2009).
