%X This study applies
Theil¡¯s second measure for looking into inequality in access to improved water
source. This index allows inequalities to be broken up within and between
groups. An analysis of 188 countries for the period 1990-2012 demonstrates
three observations: first, decline in inequality in access to improved water
source is characterized by both within-group and between-group inequality
elements; second, between-group inequalities are at present the key contributor
of the entire inequality scenario; and lastly, an inclusive study on
within-group inequalities divulges the significant role played by Central and
South American and Middle East countries towards increase in inequalities and
countries pertaining to North America, Asia and Oceania, Africa, and Europe
towards decline in inequalities.
