Classification Algorithm for Skin Color (CASCo): A new tool to measure skin color in social science research

Objective

A growing body of literature reveals that skin color has significant effects on people's income, health, education, and employment. However, the ways in which skin color has been measured in empirical research have been criticized for being inaccurate, if not subjective and biased.

Objective

Introduce an objective, automatic, accessible and customizable Classification Algorithm for Skin Color (CASCo).

Methods

We review the methods traditionally used to measure skin color (verbal scales, visual aids or color palettes, photo elicitation, spectrometers and image-based algorithms), noting their shortcomings. We highlight the need for a different tool to measure skin color

Results

We present CASCo, a (social researcher-friendly) Python library that uses face detection, skin segmentation and k-means clustering algorithms to determine the skin tone category of portraits.

Conclusion

After assessing the merits and shortcomings of all the methods available, we argue CASCo is well equipped to overcome most challenges and objections posed against its alternatives. While acknowledging its limitations, we contend that CASCo should complement researchers. toolkit in this area.     

Social policy expansion and segmentation in the first two decades of the 21st century in Latin America

Latin American countries saw an important expansion in social policy in the first two decades of the 21st century. Along with this increased inclusion, however, social policy remains segmented. Using recent data from ECLAC, World Bank, and other sources, this paper offers a comprehensive analysis of trends in social policy for the period 2000–2020 for 17 countries in Latin America. Four areas of social policy are assessed in longitudinal and comparative perspectives: transfers, health care, education, and family policies. Conditional cash transfers (CCT) and noncontributory pensions (NCP) are the two main policy innovations that allowed countries in the region to expand social rights to previously excluded populations (outsiders). At the same time, due to their design, these policies have introduced new layers of fragmentation to the welfare mix, without resolving—or even increasing—segmentation in social policy. Segmentation is still the rule for the areas of health care and education, and increasing privatisation went unabated even in the periods of social policy expansion and in the countries governed by left coalitions.
