Northfield's housing stock is largely established, single-family suburban homes, reflecting its mid-twentieth-century growth as a mainland suburb of Atlantic City. Streets are typically lined with ranches, colonials, and split-levels on modest to mid-size lots, with pockets of newer construction and smaller infill development. The community's mature trees and proximity to Birch Grove Park give many blocks a settled, leafy feel. Demand is driven by the city's convenience to Atlantic City, the AtlantiCare medical hub, and the Garden State Parkway, making it a practical base for shore-area workers and families who want a quieter setting than the barrier-island towns.

Northfield is a compact city of roughly 3.4 square miles, and its neighborhoods blend together as a continuous residential fabric rather than distinct named subdivisions. Homes concentrate along U.S. Route 9, Shore Road, and the side streets that fan out toward Birch Grove Park and the city's western edge. The area around the park is particularly sought after for its wooded setting and trail access. Commercial activity clusters along the highway corridors, while the surrounding residential blocks remain quiet. Nearby Linwood and Somers Point extend the local housing picture, and the barrier-island towns of the Jersey Shore lie just east.

Life in Northfield is suburban and unhurried, with the Jersey Shore's attractions close at hand. Residents spend time at Birch Grove Park, walking its trails, fishing the lake, or picnicking in the groves, and the city hosts seasonal events around the park. Dining, shopping, and services line the Route 9 corridor, while Atlantic City's restaurants, casinos, boardwalk, and entertainment venues are minutes away. The city's identity as the 'Gateway to the Shore' captures its role: a comfortable mainland community from which beaches, bays, and resort amenities are easily reached, without the traffic and density of the islands themselves.

Public education in Northfield is provided by Northfield Community Schools, a kindergarten-through-eighth-grade district serving the city. For grades nine through twelve, Northfield students attend Mainland Regional High School in Linwood, a regional district shared with Linwood and Somers Point. The combination gives families neighborhood elementary and middle schooling with a well-established regional high school. Nearby institutions include Stockton University in Galloway and Atlantic Cape Community College, both within commuting distance, and the broader Atlantic County region offers additional private and parochial options.

Northfield is positioned for easy regional travel. U.S. Route 9 runs north-south through the city, linking it to Linwood and Somers Point to the south and Pleasantville to the north. The Garden State Parkway and the Atlantic City Expressway, the region's two principal limited-access highways, intersect just north of the city, providing routes toward Atlantic City, Cape May, and the Philadelphia area. NJ Transit bus service, including the Route 507 line, connects Northfield to Atlantic City. Commuters heading to Atlantic City's casino and AtlantiCare medical hubs face a drive of roughly eight miles over the bays on the Black Horse Pike.

Birch Grove Park is the centerpiece of recreation in Northfield. The 271-acre municipal park offers a lake for fishing, walking and jogging trails, playgrounds, picnic groves, and a historic house and museum, and it hosts seasonal fishing tournaments and community events. Beyond the park, residents are minutes from the beaches, boardwalks, and bays of the Jersey Shore, with Atlantic City's entertainment and Ocean City's family-friendly boardwalk both within easy reach. County and regional parks add golf, sports fields, and nature trails, and the back bays offer boating and fishing for the shore-oriented.
