How has demand evolved?
The chart below tracks cumulative Part 1 demand, combined Part 1+2 demand, permissions granted, and the total outstanding demand over time.
Summary of Errors Found
- 2016-2021 Missing Breakdowns: The dataset lacked Part 1 and Part 2 breakdowns for years prior to the introduction of the Local Connection Test. All individuals and groups were assigned to Part 1 for these years as standard practice when no test is in place.
- 2017 Arithmetic Discrepancy: The reported Total Individuals End of Period (97) did not match the Start (31) + Added (64) = 95. The figure was corrected to 95 to align with the 'Added' data.
- 2019 Unexplained Drop: The reported Total Individuals dropped to 106 despite a calculated running total of 154 (previous end 116 + 38 added). No removals were recorded. The total was corrected to 154 to preserve the registration history.
- 2020 Group Arithmetic Error: The reported Group Total (1) did not match the Start (2) + Added (1) = 3. The figure was corrected to 3.
- 2022 Register Reset: The register data showed a reset (Total Start: null, End: 33) coinciding with the introduction of the Local Connection Test, effectively erasing ~263 prior registrants without recording them as 'Removed'. The totals were adjusted (End adjusted to 296) to include the historical data.
- 2022-2024 Group Disappearance: Groups dropped from 3 to 0 in 2022 without recorded removals. The count of 3 was restored for subsequent years.
- 2022 Part 1/2 Inconsistency: The 2022 reported data contained internal inconsistencies (Part 1 + Part 2 did not equal Total). The Part 1/Part 2 split for 2022 additions was derived from the verified 2023 Start of Period figures (23 Part 1, 10 Part 2).
