The case for child welfare in OECD countries: Let the data speak for itself

1 Comment

After reading an interesting piece of news titled ‘1 in 4 children in US raised by a single parent‘ I decided to explore recent OECD statistical data in more detail. Being the data geek I am, I was more than happy to find that OECD created very nice and easy-to-use visualization interfaces for many data sets related to the welfare of children:

OECD Data Visulization - Children in Poor Homes

OECD Data visualization - Children in Poor Homes

From average disposable income to inequality in literacy, from infant mortality rates to public spending figures for early childhood, it is possible to dive into the world of data and see how good your country does, compare it with other countries and learn more about the parameters OECD considers worth recording for analyzing childhood welfare.

Which countries are more child-friendly in terms of maternity leave? (Take 1)


I decided to do a very crude visualization to see which countries are more child-friendly in terms of maternity leave. I was able to find data for some countries. The data set I used is from ‘The Clearinghouse on International Developments in Child, Youth and Family Policies at Columbia University – Table 1 Maternity, Paternity, and Parental Leaves in the OECD Countries 1998-2002‘. I used Google Fusion Tables to store and visualize the data. From the OECD table I took the first maternity leave number (ml) (in weeks) and the ‘Percentage of Wage Replaced (%)’ (p) to calculate a C-friendliness (Child Friendliness Index) and my crude formula was:

C-friendliness = ml * p

(if p = 0, then p = 1).

You can examine the normal map:

Child Friendliness of Some Countries - 1

Child Friendliness of Some Countries - 1

You can also see it as an intensity map (the greener the better):
