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
- 2016-2017 Missing Breakdown: No Part 1/2 distinction provided. Data derived by assigning all totals to Part 1, assuming Part 2 (local connection test) was not yet relevant or data was unavailable.
- 2018 Individual Totals Discrepancy: The data reported a Total End of 143, but the previous year ended at 136 and 10 were added (Calculated 146). The Part 1 breakdown was adjusted (133 -> 136) to align with the historic total of 146.
- 2019 Group Arithmetic: The register reported 1 Group End, but the previous year ended with 3. With no removals reported, the Group End was corrected to 3 to maintain continuity.
- 2020 Missing Data: The entire year contained null values. Data was derived by carrying forward End values from 2019.
- 2021 Added vs. Breakdown Conflict: The Total Individuals Added was reported as 27, but the Part 1 and Part 2 breakdown columns showed increases of 3 and 34 respectively (Total 37). The Total Added was adjusted to 37 to honor the specific breakdown data (higher registrations).
- 2022 Data Entry Error (Totals vs Added): The fields for "Part 1 Individuals End" (18) and "Part 2 Individuals End" (7) summed exactly to the "Total Individuals Added" (25). This indicates the Added figures were erroneously entered into the End columns. The correct End values were derived by adding these figures to the 2021 End totals.
- 2024 Copy-Paste Error: The Total columns (Start 213, Added 11, End 224) were identical duplicates of the 2023 entry. However, the Breakdown columns contained new, albeit disjointed, data. The Totals were recalculated based on the breakdown additions (18 + 15 = 33).
- 2024 Continuity Discrepancy: The 2024 Breakdown columns reported Start values (Part 1: 250, Part 2: 198) that were significantly higher than the calculated 2023 End values (Part 1: 161, Part 2: 61). To maintain a valid register timeline, the Starts were adjusted to match 2023 Ends, and the Ends were recalculated using the numbers Added in 2024.
