Several errors were introduced after proofreading, and the authors hence wish to make the following corrections to this paper [1]:
Figure Legend
In the original publication, there was a mistake in the legend for Figure 1. The figure note “* Weighted measure. ** Weighted or unweighted measure.” was redundant as this information is included in Figure 1. The corrected legend is shown below.
Figure 1. Overview of summary measures of health inequality.
Error in Tables
In the original publication, there was a mistake in Tables A7 and A9. Several numbers in the tables were missing a decimal. The corrected Tables A7 and A9 are shown below.
Table A7.
Economic-related inequality in three reproductive, maternal and child health indicators: Indonesia (DHS: 1997, 2007 and 2017).

Text Correction
There was an error in the original publication. There were several formatting errors in Section 3. Summary Measures of Health Inequality, including sub-section headers should have been italic; summary measure names (headers) should have been bold; headers for “Definition”, “Calculation” and “Interpretation” should not have been numbered; text for “Definition”, “Calculation” and “Interpretation” should not have been italic. A correction has been made to 3. Summary Measures of Health Inequality. Please refer to the publication for the corrected text.
The authors apologize for any inconvenience caused and wish to state that the scientific conclusions are unaffected. The original publication has also been updated.
