After incorporation, Newark experienced suburban development, with new housing developments, schools, and shopping centers catering to a growing population, especially after World War II. The city's proximity to major Bay Area tech and industry hubs has influenced its character, leading to a blend of suburban life with easy access to larger job markets and urban amenities.

Today, Newark is a diverse, suburban city that benefits from its location in the Bay Area. It has become increasingly diverse, with a blend of cultures, and has maintained some of its historic industries, while also seeing more modern developments in technology and services. Newark continues to evolve, shaped by its history and its place within the dynamic Bay Area economy and culture.
