The County's population increased 97% in the 1940s from 83,912 to 164,401 and 107% in the 1950s from 164,401 to 340,928. This placed Montgomery County in competition with Los Angeles and Houston as one of the fastest growing counties in the nation. This two-decade population boom was driven by the out-migration of Washington, D.C. residents seeking relief from overcrowded living conditions and by the in-migration of job seekers from around the country attracted to post-war government and private sector jobs. The vast majority of new County residents in the 1950s were white and this caused the percentage of blacks in the County population to drop from 10.6% in 1940 to 3.9% by 1960.
The post-war increase in jobs in Montgomery County was partly driven by increased hiring at the seven Federal agencies located in the County: Army Map Service, Atomic Energy Commission, Bethesda Naval Medical Center, David Taylor Model Basin, National Institutes of Health, Naval Ordinance Laboratory, and Walter Reed Hospital Annex.
The increase was also driven by increased hiring at the private companies that established offices in Montgomery County to compete for Federal government contracts. These companies included familiar names such as Booz-Allen Research, Fisher Scientific Co., General Electric, IBM Federal Systems, Inc., Johns Hopkins Applied Physics Laboratory, Operations Research, Inc., and Vitro Corporation. (Hiebert & MacMaster, A Grateful Remembrance, The Story of Montgomery County, MD, 1976)
The increase in jobs was also boosted by increased hiring at the retail and service-oriented businesses that were serving the needs of the County's rapidly increasing population These businesses included The Hecht Company, Jelleff's, Inc., Suburban Trust Co., Peoples Drug Stores, Marriott Hot Shoppes, and Raleigh Haberdasher.
By the end of the 1950s, as the chart below indicates, Montgomery County had a 133,487-person workforce. 47% of workers were employed in the County and 53% were employed outside the County. The commonly held belief that Montgomery County was just a "bedroom community" for residents employed in Washington, DC was no longer accurate after World War II.
The post-war increase in jobs led to increases in annual incomes between 1949 and 1959, especially for down-county residents. Residents in the five down-county election districts of Wheaton, Bethesda, Rockville, Colesville, and Potomac had annual incomes ranging from $6,000 - $12,000 and up, while residents in the eight up-county districts had annual incomes ranging from $3,000 - $5,000 and up. As the chart below indicates, increases in family income in the County were not distributed equitably. "The median income of white families in 1959 was $9,350" versus a median income of $4,475 for non-white families. (Montgomery County Chamber of Commerce, 1960-61 Montgomery County Handbook, 1960)
The bi-county Washington Suburban Sanitary Commission (WSSC) was established in 1918 in response to complaints from the District of Columbia that sewage waste from Montgomery and Prince George's County streams was polluting Rock Creek Park. Its jurisdiction was restricted to the lower part of each county.
The WSSC utilized low interest bonds to construct a network of trunk sewer lines along stream valleys in each County. These sewer lines connected to the Blue Plains Sewage Treatment Plant located on the Potomac River near the mouth of the Anacostia River in the District of Columbia.
The WSSC also used low-interest bonds to construct a network of water lines to service homes in the down-county. During the 1950s housing boom, the WSSC rapidly connected water and sewage lines to new housing subdivisions.
Today, the WSSC continues to serve as the water and sewage authority for Montgomery County and Prince George' Counties.

Source: 1960-61 Montgomery County HandbookMontgomery County residents had good access to jobs and shopping in Washington, DC through the network of existing roads (Massachusetts Avenue, River Road, Old Georgetown Road, Wisconsin Avenue, Connecticut Avenue, Georgia Avenue, 16th Street, Colesville Road, and New Hampshire Avenue) as shown in the map above. The dark lines indicate roads being expanded in response to increased residential development in the 1950s. In addition, East-West Highway, University Boulevard, and Viers Mill Road provided much needed cross-county roads for residents traveling to jobs within the County.
The County also had excellent bus service to and from DC as shown in the bus route map below. DC Transit established new bus routes to serve the suburban communities of Colesville, White Oak, Four Corners, Silver Spring, Forest Glen, Glenmont, Wheaton, Rockville, Kensington, Garrett Park, Chevy Chase, Bethesda, Glen Echo, Cabin John, and Potomac.

The M-NCPPC established separate county planning boards to oversee park and planning operations in each jurisdiction.
The Montgomery County Planning Board hired experienced planning professionals to evaluate zoning regulations and subdivision applications. The goal was to maintain the quality of community life, preserve property values, and respond to rapid post-war growth. One way the Planning Board helped maintain property values and the quality of community life was to separate residential development from commercial development and separate industrial areas from both.
Another innovative way planning professionals responded to the post-war housing boom was by establishing a policy requiring subdivision applicants to dedicate a portion of their undeveloped land to accommodate the location of future utilities, streets, schools, and parks. This policy enabled Montgomery County to secure land needed to expand existing, or build new, infrastructure to support future growth while avoiding the time and expense of acquiring land through condemnation or eminent domain.

The Capper-Cramton Act passed by Congress in 1930 provided the initial funding for the Commission to acquire land for parks. The M-NCPPC bought 900 acres of land in the Little Falls Creek, Rock Creek, Sligo Creek, and Northwest Branch stream valleys and staff began to implement a sophisticated plan for an extensive bi-county park system. The Commission built parks and recreation facilities in these locations and designed automobile parkways to give residents access to outdoor park and recreation experiences. In addition, the M-NCPPC worked with the Montgomery County & Prince George's County Public School Boards of Education to locate recreation and sports facilities close to new elementary, junior high and senior high schools.
By 1959, the combination of a good plan, aggressive land acquisition, and effective coordination with school systems produced a national award-winning bi-county park system with thirteen miles of parkways and 3,539 acres of public park land. The park system had community recreation centers; neighborhood and regional playgrounds; outdoor grills and fireplaces; baseball, softball and football fields; tennis courts; drinking fountains; picnic tables; and other recreation amenities.
In Montgomery County alone, residents had access to the 679-acre Rock Creek Park, 159-acre Sligo Creek Park, 65-acre Cabin John Park, and Jessup Blair Park in Silver Spring plus a wide range of outdoor and indoor summer recreation programs for youth.
