Because an MPI incorporates multiple dimensions, it can promote integrated and collaborative policies across a subset of SDG indicators, while prioritizing the poor. According to a July 2015 UNGA document the SDGs are providing "a stronger incentive than in the past for cross-sector, integrated and collaborative work. Similarly, to evaluate progress under the sustainable development goals, it will be necessary to look at multiple goals concurrently and in an integrated fashion." It recognises the need for "United Nations agencies, funds and programmes concerned with a specific goal (e.g., education, health, economic growth)" to take into account targets that refer to other goals". Because the MPI has multiple indicators it is often mistakenly presumed that the time and cost of surveys is higher.
