Tracking the Changing Child Population in Montgomery County

Posted: by

By Alanna Anderson and James Lee

Montgomery Planning’s Research and Strategic Projects Division periodically develops demographic profiles of Montgomery County population groups by analyzing the latest data from the U.S. Census Bureau and other sources. These profiles provide important information to planners and decision makers to help them understand a population’s characteristics and create equitable and inclusive communities for current and future generations. In April 2026, the division released its Children in Montgomery County Profile, and this blog summarizes several key findings.

A big change in population share

The Census Bureau’s latest American Community Survey (ACS) data show there were more than 243,000 children (ages 17 years and younger) in Montgomery County in 2024—that’s 54,471 more than in 1970. … Continue reading

Reimagining federal property in Montgomery County: Turning challenges into opportunities

Posted: by

The recent downsizing of federal agencies is having a real and immediate impact on Montgomery County—displacing workers and leaving many with uncertain futures. These changes are difficult, especially for those whose livelihoods have long been tied to federal employment. At the same time, this moment calls on land use planners to think strategically about what comes next, as it may no longer be a given that the federal government will occupy the same building and campus footprints that it has in the past. If certain federal properties are no longer needed for government use, we may have an opportunity to reimagine how these sites could serve our communities in new ways. This blog provides an overview of federal property … Continue reading

The false choice between redevelopment and displacement: How investment can promote inclusive growth and prevent decline

Posted: by

People are often nervous about large redevelopment plans in their neighborhoods. This wariness is understandable because there is a long history of redevelopment and exclusionary practices directly and indirectly displacing people—often people of color.1

As Montgomery Planning continues to work with the community reenvisioning some of its mature neighborhoods like eastern Silver Spring and corridors like University Boulevard a retrospective look at some recent notable redevelopments could address some of these concerns and provide lessons for current and future plans. This analysis highlights two key facts about redevelopment plans in Montgomery County.

Some of the county’s most notable redevelopment efforts have produced equitable and inclusive growth. In neighborhoods and corridors where evolution is stalled, the alternative to redevelopment is … Continue reading

Time for a Reality Check: How are we doing with the 2002 Potomac Subregion Master Plan?

Posted: by

 

Master plans are created as ambitious visions for the future with recommendations for land uses, zoning, transportation, schools, parks, and other community facilities. We write them to guide development during the decades that lie ahead, using our best predictions of how population and priorities will change over those years. To assess the progress of a master plan, it’s beneficial to conduct a reality check as the master plan approaches its horizon date (20 years since adoption). A reality check can help us evaluate how well a master plan has been implemented, understand whether its visions have been achieved, and identify which recommendations worked as anticipated.

With these objectives in mind, the Montgomery County Planning Department initiated the Master … Continue reading

Century of change: Where we are after 100 years of homebuilding in Montgomery County

Posted: by

An analysis of Montgomery County’s property assessment database over the past century shows homebuilding consistently increased before peaking in the 1980s and has since slowed substantially. The data also show how the composition of the housing stock has changed over time, from overwhelmingly single-family to many more townhouses and apartments.

From before the 1920s through the 1980s, each successive decade saw more homes built than the decade before, except for the 1970s. Then, starting in the 1990s, the trend reversed, with a sharp drop-off in new homes from the 1980s. The decline continued through 2019. Data for 2020 to 2022 suggest that the county may be on pace for another decade of decline.

By Bhavna Sivasubramanian

In honor of Women’s History Month, the Research and Strategic Projects Division at Montgomery Planning developed a profile presenting key demographic, economic, and employment characteristics of the female population in Montgomery County. Gender disparity is a national and global topic of study, and this research aims to highlight such differences in the county. Considering the unique characteristics and challenges faced by females in the county helps planners, local government decision-makers, and the public develop equitable, diverse, and inclusive communities for all. All data for this research come from the U.S. Census Bureau’s 2022 American Community Survey (ACS) 1-year estimates. Data are from respondents who answered “Female” to ACS’s question “What is your sex?”

In 2022, women … Continue reading

Repositioning Montgomery County for Prosperity, Part 3: Abundant Housing for Inclusive Growth

Posted: by

The previous two blogs in this series summarized the Navigating Income Shifts in Montgomery County: Towards Shared Prosperity research brief that describes how disproportionate changes along the income distribution underlie Montgomery County’s stagnating incomes. The low-income population has been increasing rapidly, while the middle-income segment is shrinking, and the high-income population, though growing in absolute terms, has not increased as a share of the population.

This final blog in the series discusses why this trend is a problem and what Montgomery County can do about it. As a reminder, the expansion of the low-income population, by itself, is not a problem. Rather, it should be seen as a success and a validation of Montgomery County’s welcoming and diverse values, … Continue reading
