Five years of implementation examples: countries and institutions including refugees, internally displaced persons and stateless persons in official statistics, and applying the International Statistical Recommendations developed by EGRISS.
Each circle is one example reported to GAIN. Twinkling ones open a report or source page; teal glints have an EGRISS case study. Hover or tap. Scroll ↓
413 examples were reported to the GAIN Survey between 2021 and 2025. Each circle is one example.
An example can be a data source, such as a census, survey, administrative data or data integration, or a tool, such as a strategy, guidance, toolkit, workshop or training.
Country-led, using the Recommendations
Institution-led, using the Recommendations
Hollow: not using, or don't know if used
Adoption of the Recommendations remained high in 2025, with 81 per cent of country-led and 74 per cent of institution-led examples applying them, despite a challenging landscape and a decline in country-led examples.
A total of 117 examples were reported in 2025: 63 country-led and 54 institution-led. Filled circles are examples using the Recommendations; hollow ones are not using them or don't know. The number on top of each bar counts all examples, the number below those using the Recommendations.
14 examples applied IROSS alone, all reported after IROSS was adopted in 2023.
In the Philippines, the statistics authority used IROSS to bring people at risk of statelessness into civil registration, including undocumented Filipinos in Sabah. A 2026 EGRISS case study tells the story.
Expanding civil registration and administrative records to include people at risk of statelessness ↗Each example is statistical work by a national statistical system or an institution. In the Philippines, the statistics authority applied IROSS in a birth registration project, reported to GAIN in 2024.
Expanding civil registration and administrative records to include people at risk of statelessness ↗ Strengthening national ownership in data collection and analysis on internal displacement ↗26 EGRISS case studies tell the story behind 42 of these examples. The highlighted ones have case studies published in 2025 and 2026.
Throughout the charts, a bright teal ring marks a recent case study and a faint ring an earlier one. Point at a ringed example to see the others its case study covers.
All country case studies ↗IRIS-only examples surpassed IRRS-only examples for the first time since 2022, with 34 and 27 examples respectively, driven by a rise in institution-led IRIS implementation.
LATEST ROUNDEach chart first shows the newest results, GAIN 2025, then opens up to ALL ROUNDSsince 2021. Examples from other rounds, or outside a chart, stay in the background as faint circles. The 91 examples using the Recommendations in 2025 form the ring: IRIS 34, IRRS 27, mixed use 24, undetermined 4 and IROSS 2.
Each mixed-use circle is split into the Recommendations it combines. All three Recommendations combined was the most common mix (11), followed by IRRS and IRIS (10) and IRRS and IROSS (3). No IRIS and IROSS examples were reported in 2025.
The inner ring splits them by example lead: 51 country-led and 40 institution-led.
Institution-led examples using the Recommendations rose from 19 in 2024 to 40 in 2025, while country-led examples using them fell from 87 to 51.
The same 91 examples sorted by lead: 51 country-led, by national statistical offices and other government entities, and 40 institution-led, by international, regional and civil society organizations. The faded inner ring keeps the breakdown by Recommendation in view.
Across five rounds, 337 examples used the Recommendations: 207 country-led and 130 institution-led.
IRRS remains the most used overall (123), followed by mixed use (99) and IRIS (93). IROSS, adopted in 2023, accounts for 14. Use the Year buttons above the ring to see any single round.
Africa reported the highest number of country-led examples in 2025. Among those using the Recommendations, the region accounted for almost half of all country-led examples (23 of 51).
Europe follows with 12. Point at a small globe to pick out its region. Keep scrolling to see all five rounds.
Incorporating IRIS and IRRS into the 2025 Survey on Household Living Conditions ↗Africa accounts for the most country-led examples using the Recommendations across all rounds: 91 of 207 since 2021.
Europe follows with 44, then the Americas 35, Asia and Oceania 20 and the Middle East 17.
Surveys remained the most common data source for country-led examples.
Data sources are a multiple-choice question: an example can report more than one. From here an example appears once for each answer, and examples that appear more than once are ringed in white. The 63 country-led examples of 2025 reported 94 data sources: surveys 32, administrative data 30.
Hover over an example to highlight its other answers.
Across both rounds that asked about data sources, surveys and administrative data stay well ahead.
160 country-led examples reported 249 data sources in 2024 and 2025: surveys 84, administrative data 75, census 36 and Tools and Other 26. GAIN first asked about data sources in 2024.
While most examples did not report challenges, resource constraints were the top challenge among those that did (25), jumping ahead of any other challenge compared with 2024.
Challenges are also multiple-choice. 48 examples reported 120 challenges between them, so an example that reported three challenges appears three times, ringed in white. Identification of populations follows with 15.
Resource constraints and identification of populations are the most reported challenges across both rounds.
84 examples reported 206 challenges in 2024 and 2025: resource constraints 40, identification of populations 32, then safety concerns and political issues with 27 each.

Filled circles are examples using the Recommendations; hollow ones are not using them or don't know. Each country's examples rise from it as a column, with the count on top, and countries with examples are shaded teal as in the GAIN Tables maps.
