Croatia: Immunization, HepB3 (% of one-year-old children)

Key figures

What the numbers say

In 2024, Croatia's immunization, HepB3 (% of one-year-old children) fell 1 percentage points on 2023 (from 92% to 91%).

Across the 16 yearly changes before that (2008 to 2023), the average change was −0.13 percentage points and a typical year strayed about 1.31 percentage points from that (the standard deviation). This year's change was 0.7 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 3 percentage points in 2008 and the biggest yearly fall was 2 percentage points in 2016. 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 the straight-line trend is downward, about 0.29 percentage points a year. A straight line explains 45% of the movement over 10 observed years.

What this measures

Child immunization rate, hepatitis B is the percentage of children ages 12-23 months who received hepatitis B vaccinations before 12 months or at any time before the survey. A child is considered adequately immunized after three doses.

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.
