A Tool for Estimating and Visualizing Poverty Maps.

SDG: 01 - No Poverty

As increasingly more people seek to live in urban cities, governments and other organizations face the challenge of effectively identifying areas in most need of revitalization and intervention.

One way of designing such interventions is by using “poverty maps”.

Poverty maps are designed to simultaneously display the spatial distribution of welfare and different dimensions of poverty determinants. The plotting of such information on maps however heavily relies on data that is collected through infrequent national household surveys and censuses. However, due to the high cost associated with this type of data collection process, poverty maps are often inaccurate in capturing the current deprivation status.

In this project, we address this challenge by means of a methodology that relies on alternative data sources from which to derive up-to-date poverty indicators, at a very fine level of spatial granularity. We validate our methodology for the city of Milano. Based on our methodology and design requirements gathered from stakeholders we design and implement a poverty mapping tool for policy makers.

Project Objective:

Exploration, Other, Scientific / research

Project Outcomes:

To build a a tool that can estimate and visualise poverty maps for any region in the world. The tool allows the user to upload a CDR file, and in case of no CDR it relies on prediction based on OSM only (using API).

Data Quality
Data Quality
Quality Aspects Evaluated: Validity, Accuracy, including selectivity
Validation Comments: Ground truth data about poverty collected from last Italian census available from iStat
Quality Framework Comments: Both quantitive and qualitative. Quantitive evaluation of the prediction model and qualitative model of the poverty maps.
Data Quality Concerns Comments: As iStat does not provide a single composite index of poverty we needed to construct this value based on multiple variables such as unemployment, education etc. by using Principle Component Analysis.
