Click here for research on the effects of land use planning and gentrification on Portland’s communities of color and other vulnerable populations. Economic Vulnerability Assessment: This map identifies census tracts in Portland where residents are more vulnerable to changing economic conditions, making resisting displacement more difficult. These areas have residents who are more likely to: Be "housing cost-burdened", meaning they pay 30% or more of their income on housing costs. Belong to communities of color, particularly Black and Indigenous communities. Lack college degrees, and Have Lower Incomes. This dataset provides an update to the vulnerability risk analysis that Dr. Lisa Bates prepared for the Bureau of Planning and Sustainability in 2012. This latest dataset includes the following changes in methodology: Low income households were replaced with a size-adjusted median household income. This helps account for how different household sizes experience living with different incomes. Renter households were replaced with households that are housing cost-burdened (pay 30%+ on housing costs). This acknowledges that homeowners who pay a high percentage of their income on housing can be vulnerable to displacement as well. A new variable, Black and Indigenous population, was added to better incorporate past harms to these communities. The vulnerability score was rescaled from 0 to 100. A score of 60 or greater is considered a vulnerable tract. Data sources: U.S. Census Bureau, 2022 ACS 5-year estimates, Tables B25106, B25010, B03002, B19013, B15002.

点击此处查看关于土地利用规划与绅士化(gentrification)对波特兰有色人种社区及其他脆弱群体影响的研究。 经济脆弱性评估:本地图识别出波特兰市内居民更易受经济环境变化影响、难以抵御流离失所风险的普查区域(census tract)。 这类区域的居民更大概率具备以下特征:属于住房成本负担(housing cost-burdened)群体,即住房支出占收入的30%及以上;隶属于有色人种社区,尤其是黑人与原住民社区;未取得大学学历;收入水平较低。 本数据集是对2012年丽莎·贝茨博士为规划与可持续发展局(Bureau of Planning and Sustainability, BPS)编制的脆弱性风险分析报告的更新版本。 本次更新的数据集在方法论上做出了以下调整:将低收入家庭指标替换为经家庭规模调整后的家庭收入中位数,以更准确反映不同家庭规模对收入水平的实际承受情况;将租房家庭指标替换为存在住房成本负担(住房支出占收入30%及以上)的家庭,这一调整覆盖了同样面临高额住房支出压力、可能遭遇流离失所风险的自有住房群体;新增“黑人与原住民人口”变量,以更好体现过往对这些社区造成的伤害;将脆弱性评分的取值范围重新缩放为0至100,评分达到60及以上的普查区域将被视为脆弱区域。 数据来源:美国人口普查局,2022年美国社区调查(American Community Survey, ACS)5年估计数据,涉及表格B25106、B25010、B03002、B19013、B15002。 本数据集由波特兰规划与可持续发展局于2024年夏季编制,可从波特兰市开放数据网站下载。 关于规划与可持续发展局:波特兰规划与可持续发展局(Bureau of Planning and Sustainability, BPS)致力于制定兼具创新性与实用性的解决方案,以提升波特兰的宜居性、保护特色地域风貌并规划韧性未来。 如需获取更多数据相关信息,请发送邮件至bpsgis@portlandoregon.gov。——补充信息:类别:规划;用途:绘制易受绅士化压力影响的区域;更新频率:每年;元数据链接:https://www.portlandmaps.com/metadata/index.cfm?&action=DisplayLayer&LayerID=54141
