Real-world modernization projects — how we help National Statistical Offices transition to register-based systems, improve data quality, and deliver better statistics.
Designing a Long-Term Register-Based Statistical Information Model
Middle East National Statistical Office · Rapid Statistical Modernization Programme · Aligned with National Vision 2030
Challenge
The National Statistical Office sought to fundamentally transform its statistical production model — moving away from costly, infrequent traditional censuses toward a continuous, register-based system aligned with its National Vision 2030 strategy. While the country possessed strong administrative assets (a national ID system, address register, civil events, business licensing, and education records), these sources operated in silos with inconsistent identifiers, incomplete linkage keys, and no shared temporal governance framework. The NSO needed a comprehensive long-term information model that could translate these administrative pillars into coherent, reproducible official statistics.
Approach
EnStatX led the design of a long-term register-based statistical information model, translating Nordic register-based practice into the national context. The work was structured around the GSBPM framework and involved:
- Defining a two-tier register architecture — Primary Statistical Registers (Persons, Addresses, Buildings, Legal Units, Enterprises, Establishments) and Secondary Statistical Registers (Jobs, Income, Education, Vital Events, Residence Spells) — with standardised identifiers and bi-temporal versioning
- Mapping existing administrative sources (national QID, address system, civil events, tax/business registers, education data) against statistical requirements, identifying coverage gaps and linkage inconsistencies
- Designing a conceptual model with explicit unit types, population definitions, reference time rules, and quality governance for each register
- Producing a short-term information model with priority output tables (Population, Household, Employment, Business Demography, Housing) ready for immediate implementation
- Aligning the full framework with GSBPM/GAMSO process standards, UN-NQAF quality management, SDMX metadata standards, and the national QDTI quality framework
- Deploying AI/ML solutions to support automated record linkage, address geocoding, and statistical imputation at scale
Standards Applied
- GSBPM v5.1 — end-to-end process alignment
- UN-NQAF — quality assurance framework
- SDMX — structural and reference metadata
- DDI — variable-level documentation
- ISCO / ISIC / ISCED — international classifications

Continuous Population Survey — Household Survey Programme Redesign
Statistics South Africa (Stats SA) · CPS-HSPR Project · Preparing for the 2027/28 National Survey Rollout
Challenge
Statistics South Africa faced the challenge of fundamentally modernising its national survey infrastructure ahead of the 2027/28 Continuous Population Survey (CPS). The existing survey systems needed to be made more agile, inclusive, and aligned with international best practices. Four critical operational frameworks — the Geo-statistical Framework, the Integrated Operations Model (IOM), the Survey Monitoring and Evaluation Framework, and the Communication, Publicity and Advocacy Strategy — required comprehensive review, field-testing, and operationalization. At the same time, Stats SA needed to build internal capacity to independently sustain and evolve these frameworks after the project concluded.
Approach
EnStatX provided senior technical consultancy across a structured 24-month, six-phase programme covering the full cycle from framework review to national rollout planning. Key work streams included:
- Reviewing and validating the Geo-statistical Framework (GIF) — including enumeration area delineation, GPS-based geocoding, and alignment with the national Master Sampling Frame (MSF)
- Conducting on-site field missions to test the GIF and IOM under live field conditions, validating geospatial workflows and identifying logistical constraints in hard-to-reach areas
- Designing and reviewing mixed-mode data collection strategies (CAPI, CATI, and hybrid CAPI/CATI), measuring response rates, data accuracy, cost-efficiency, and respondent satisfaction across regions
- Assessing the Survey Monitoring and Evaluation Framework during pilot fieldwork, including real-time dashboards, quality flags, and automated validation systems
- Evaluating the impact of the Communication, Publicity and Advocacy Strategy and recommending improvements to respondent cooperation and stakeholder engagement
- Delivering a structured skills transfer programme — 11 targeted workshops aligned to each deliverable — to ensure institutional sustainability beyond the project lifecycle
- Producing a comprehensive CPS 2027/28 rollout plan and reviewing alternative methods for collecting household expenditure data within a continuous survey model
Project Phases
- Phase 1 — Framework Reviews & Planning (Dec 2024 – May 2025)
- Phase 2 — Geo-statistical Framework Feasibility Testing (Jul – Aug 2025)
- Phase 3 — Mixed-Mode Methodology Testing (Jan – Mar 2026)
- Phase 4 — Full Implementation Testing & Assessment (Sep – Nov 2026)
- Phase 5 — CPS Rollout Planning & Methodological Refinement (Oct – Dec 2026)
- Phase 6 — Final Reporting & Institutional Learning (Dec 2026)
