That\u2019s why the county\u2019s growth rules, known as the Subdivision Staging Policy or SSP, prohibit new residential development in any school cluster where the schools are at 120 percent of capacity.<\/p>\r\n<p>The \u201cannual school test,\u201d which determines whether a school cluster goes into a residential development moratorium, is applied in July of each year. The impact of a development moratorium is felt as new residential projects in an area are put on hold and, in some cases, subsequently fail to move forward at all because of market changes or the loss of financing.<\/p>\r\n<p>The SSP is based on the common sense idea that growth should not get ahead of the public infrastructure needed to support it. One problem is that school enrollment growth does not track the overall rate of population growth as closely as you might think. This graph shows the relationship between Montgomery County Public Schools (MCPS) enrollment and the county\u2019s population over the past few decades, with the school enrollment and total population indexed at 100 in 1990:<\/p>\r\n<p><iframe id=\"datawrapper-chart-yAI4d\" style=\"width: 0; min-width: 100% !important;\" src=\"\/\/datawrapper.dwcdn.net\/yAI4d\/1\/\" height=\"464\" frameborder=\"0\" scrolling=\"no\"><\/iframe><script type=\"text\/javascript\">!function(){\"use strict\";window.addEventListener(\"message\",function(a){if(void 0!==a.data[\"datawrapper-height\"])for(var t in a.data[\"datawrapper-height\"]){var e=document.getElementById(\"datawrapper-chart-\"+t);e&&(e.style.height=a.data[\"datawrapper-height\"][t]+\"px\")}})}();<\/script><\/p>\r\n<p>Enrollment shrank during the 1970s and 80s. The Baby Boom was over and MCPS was closing and repurposing schools as a larger proportion of the adult population aged out of their child-bearing (and raising) years. Beginning around 1990, a smaller but still significant demographic wave washed over the county and the rate of school enrollment growth began to outpace overall population growth. Many of the schools closed in the previous decades were now unavailable to absorb new students.<\/p>\r\n<p>This long-term growth wave has continued. MCPS enrollment is expected to grow by about 11,000 students over the next six years:<\/p>\r\n<p><iframe id=\"datawrapper-chart-GZ1QQ\" style=\"width: 0; min-width: 100% !important;\" title=\"Actual (2000-2018) and Projected (2019-2024) MCPS Enrollment\" src=\"\/\/datawrapper.dwcdn.net\/GZ1QQ\/3\/\" height=\"451\" frameborder=\"0\" scrolling=\"no\" aria-describedby=\"Since 2000, MCPS enrollment has increased by about 1,600 students per year. Enrollment is projected to grow through 2024 adding another 11,199 students.\"><\/iframe><script type=\"text\/javascript\">!function(){\"use strict\";window.addEventListener(\"message\",function(a){if(void 0!==a.data[\"datawrapper-height\"])for(var t in a.data[\"datawrapper-height\"]){var e=document.getElementById(\"datawrapper-chart-\"+t);e&&(e.style.height=a.data[\"datawrapper-height\"][t]+\"px\")}})}();<\/script><\/p>\r\n<p>Eventually, this wave will recede and the rate of growth in the school-age population will sink below the rate of growth in the all-ages population. Some demographic forecasts show this decrease happening within the coming decade. Other factors also influence the size of the MCPS population, such as the relative share of students in private versus public schools. In any event, the lesson here is that (at least for now) the number of schoolchildren is \u00a0growing faster than the overall rate of population growth <em>and these kids will be in our schools whether or not more housing is built.<\/em><\/p>\r\n<p>The relationship between the number of people who live in a specific neighborhood and the number of school-age children in that neighborhood varies even more widely than at the countywide level. In addition to the broad demographic trends that produce baby booms and busts at the national or regional level, neighborhoods go through their own cycles.<\/p>\r\n<p>The consequence of this boom-and-bust cycle in individual neighborhoods is that areas popular with young families tend to see sharp spikes in school enrollment, even when there is little or no new residential development. This phenomenon is at work today in six county high school clusters at risk of entering a development moratorium in July.

A total of 22 MCPS students lived in these new homes in 2015. Yet during the same time period, the Quince Orchard cluster\u2019s enrollment grew by 532 students.<\/p>\r\n<p>What about the Blair cluster, which has seen construction of new apartment buildings? During the same time period, enrollment in the Blair cluster grew by nearly 1,100 students while over 1,400 new units of multifamily residential were built. Surely, that many apartments must be a major cause of the overcrowding, right? Address and enrollment data show that only 51 MCPS students live in these apartments \u2013 <em>less than five percent of the total growth in enrollment. <\/em><\/p>\r\n<p>The story is the same for the other clusters on the brink of entering development moratoria.

Three years later, in 2018, these same units continue to generate students at a rate approximately 70% below similar units across the six clusters. \u00a0How is this possible?
