Located within the Raritan Valley region, Cranbury is roughly equidistant between New York City and Philadelphia, contributing to it being a regional historical, cultural, and commercial hub of Central New Jersey (the township is known for its logistics industry) and as an outer-ring commuter suburb of New York City within the New York metropolitan area.Capuzzo, Jill P.

"The average homeowner’s municipal tax payment in Cranbury Township is set to reach a historic low in 2019 with a reduction of about $650 on average, and the rate could stay flat for the next two years, according to Mayor Jay Taylor. The municipal tax rate already stayed flat in 2017 and 2018....

Both Route 130 and the New Jersey Turnpike run through the small Middlesex County township, making it an ideal location."
