El Salvador: Immunization, measles (% of children ages 12-23 months)

Key figures

What the numbers say

In 2024, El Salvador's immunization, measles (% of children ages 12-23 months) fell 3 percentage points on 2023 (from 99% to 96%).

Across the 30 yearly changes before that (1994 to 2023), the average change was +0.43 percentage points and a typical year strayed about 7.21 percentage points from that (the standard deviation). This year's change was 0.5 standard deviations below that average, so it was an ordinary year: it sits within the range of normal year-to-year movement.

On record, the biggest yearly rise was 31 percentage points in 1993 and the biggest yearly fall was 44 percentage points in 1991. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.

From 2015 to 2024 there is no clear straight-line trend: a straight line explains 1% of the movement over 10 observed years, so the value is moving around more than it is heading anywhere.

Worked out from the yearly values above. How the checks work: standard deviation, z-scores and straight-line trends.

What this measures

Child immunization, measles, measures the percentage of children ages 12-23 months who received the measles vaccination before 12 months or at any time before the survey. A child is considered adequately immunized against measles after receiving one dose of vaccine.

Limitations: In many developing countries a lack of precise information on the size of the cohort of one-year-old children makes immunization coverage difficult to estimate from program statistics.

Regional and income-group figures are computed by the World Bank as a weighted average.
