| Value | Year | |

| Latest | 86.68% | 2024 |
| Five years earlier | 90.35% | 2019 |
| Ten years earlier | 89.5% | 2014 |

Over five years it is down 3.67 percentage points from 90.35% in 2019. Since 1980 it is up 55.12 percentage points from 31.56% in 1980.
In 2024, Small states' immunization, DPT (% of children ages 12-23 months) rose 0.2 percentage points on 2023 (from 86.48% to 86.68%).
Across the 30 yearly changes before that (1994 to 2023), the average change was +0.14 percentage points and a typical year strayed about 1.37 percentage points from that (the standard deviation). This year's change was 0.0 standard deviations above 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 10.09 percentage points in 1981 and the biggest yearly fall was 5.89 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 the straight-line trend is downward, about 0.37 percentage points a year. A straight line explains 44% of the movement over 10 observed years.

Child immunization, DPT, measures the percentage of children ages 12-23 months who received DPT vaccinations before 12 months or at any time before the survey. A child is considered adequately immunized against diphtheria, pertussis (or whooping cough), and tetanus (DPT) after receiving three doses 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.
