In major metropolitan areas, gentrification, financialisation and welfare retrenchment contribute to a severe housing crisis. Over the past 20 years, home price inflation and affordable housing shrinkage have been particularly acute in Paris. Such issues have been linked to the displacement of lower-income Parisians and the suburbanisation of poverty on a regional scale. In this article, we match disaggregated data from the Family Benefits Fund (CAF) with information on local housing markets, to empirically document these expulsionary processes. Our methodology is twofold. First, we investigate out-migration factors using logistic regressions. Second, we compare households’ changes in access to the city centre and urban resources following a move. Data show that social vulnerability is associated with a greater risk of leaving Paris and that housing welfare is playing a crucial role in mitigating this risk. Also, the higher the pressure on local housing markets, the more social inequalities determine mobility behaviour. Finally, beyond the effects of family structure, patterns of decentralisation are related to income level: less affluent households go farther from the city centre, job opportunities and services than higher-income households.

那些离开的人：中产化巴黎的福利受益人的外流和权力下放

在主要大都市地区，高档化、金融化和福利紧缩导致了严重的住房危机。过去20年来，巴黎的房价上涨和经济适用房萎缩尤为严重。这些问题与低收入巴黎人的流离失所以及区域范围内贫困的郊区化有关。在本文中，我们将家庭福利基金 (CAF) 的分类数据与当地住房市场的信息进行匹配，以实证方式记录这些驱逐过程。我们的方法是双重的。首先，我们使用逻辑回归研究外迁因素。其次，我们比较了搬家后家庭进入市中心和城市资源的变化。数据显示，社会脆弱性与离开巴黎的更大风险相关，而住房福利在减轻这种风险方面发挥着至关重要的作用。此外，当地住房市场的压力越大，社会不平等对流动行为的影响就越大。最后，除了家庭结构的影响之外，权力下放的模式还与收入水平有关：较不富裕的家庭比高收入家庭更远离市中心、就业机会和服务。
