People of Delmar, DE
The people of Delmar, Delaware today number 2,386, forming a small but diverse community that straddles the state line with Maryland. The city’s identity is shaped by a 59.3% white majority alongside a significant 25.6% Black population, a growing Hispanic community at 8.0%, and a small but notable Indian-subcontinent presence at 2.1%. With just 20.9% of adults holding a college degree, Delmar remains a working-class town where family roots run deep and newcomers often arrive for affordable housing and proximity to Salisbury, MD, and the Delaware beaches.
How the city was settled and grew
Delmar’s founding is tied directly to the railroad. The city was established in 1859 as a stop on the Delaware Railroad, with its name a portmanteau of the two states it straddles. The original population was drawn by the promise of rail-related work and the fertile farmland of the Nanticoke River watershed. Early settlers were predominantly white farmers and tradesmen from the Eastern Shore of Maryland and Delaware, many of English and Scots-Irish descent. The historic Railroad Avenue district became the commercial and social heart of the original town, where these founding families built homes and businesses. A second wave arrived in the late 19th and early 20th centuries as the area’s peach and strawberry canning industries boomed, attracting Black laborers from the surrounding rural counties. These workers settled in what is now known as the West Side neighborhood, west of the railroad tracks, where many of their descendants still live today. By 1900, Delmar’s population was roughly 70% white and 30% Black, a ratio that held steady through the mid-20th century.
Modern era (post-1965)
The post-1965 immigration reforms had a muted effect on Delmar compared to larger Delaware cities. The city’s foreign-born population remains low at just 3.5%, and the major demographic shifts since the 1970s have come from domestic migration rather than international arrivals. The most significant change was the expansion of the East Delmar subdivision in the 1980s and 1990s, which attracted white families moving out of Salisbury and the more expensive Delaware beach towns. This development reinforced the white majority in the eastern half of the city. Meanwhile, the Black population concentrated in the West Side and the newer Pine Grove Estates area, which was built in the 1990s and drew Black families from Sussex County’s rural communities. The Hispanic share—now 8.0%—began rising in the early 2000s, driven by Mexican and Central American workers in the poultry processing plants of nearby Millsboro and Georgetown. These families have settled primarily in the South Railroad Avenue corridor, where rental housing is more available. The Indian-subcontinent population (2.1%) is a very recent arrival, largely professionals employed at the nearby TidalHealth Peninsula Regional hospital in Salisbury or at the University of Delaware’s satellite campus in Georgetown. They have no single concentrated neighborhood, instead dispersing into the East Delmar and newer Heritage Creek subdivisions.
The future
Delmar’s population is slowly diversifying, but the pace is modest. The white share has declined from roughly 70% in 2000 to 59.3% today, while the Hispanic share has grown from under 2% to 8.0% in the same period. The Black population has remained stable at around 25-27%, suggesting neither significant out-migration nor new arrivals. The Indian-subcontinent community, while small, is growing steadily as medical professionals seek affordable housing within commuting distance of Salisbury. The East/Southeast Asian share (0.6%) is negligible and unlikely to change. The city is not tribalizing into hostile enclaves, but distinct residential patterns persist: the West Side remains predominantly Black, East Delmar and Heritage Creek are overwhelmingly white, and the South Railroad corridor is becoming a Hispanic-majority area. The biggest wildcard is housing affordability. Delmar’s home prices remain below the Delaware average, which could attract more white and Hispanic families priced out of coastal Sussex County. If that trend accelerates, the city may see its white share stabilize or even increase slightly, while the Hispanic share continues its gradual rise. The Black population is likely to remain steady as a core community with deep local roots.
For someone moving in now, Delmar is a small, affordable town where demographic change is happening slowly and without major friction. The city remains predominantly white and Black, with a growing Hispanic presence that is still small by regional standards. New arrivals will find a place where neighborhoods still reflect historical settlement patterns, but where daily life is generally quiet and neighborly. The biggest practical consideration is the state-line tax difference—Delaware side residents pay no sales tax, while Maryland side residents do—which subtly shapes where people choose to buy homes.
