The Us Partnership on Mobility from Poverty looked at what it would take to dramatically increase mobility from poverty. Their definition of mobility includes three core principles: economic success, power and autonomy, and being valued in the community.
In 2018, they released a Brief and a related capacity building Toolkit. As part of this toolkit, they also provide a Measure Selector that features a filterable listing of different measures to allow your organization to identify the best measures for your project. These measures are categorized by three factors - power and autonomy, being valued in community, and economic success.
