Affordable Housing
Appendix C
Summary of Analysis
Having considered the key stages of the Basic Needs Assessment Model, we can summarise the total need for affordable homes and the likely supply of properties. Figure 3E.1 summarises the total need for affordable homes in terms of Backlog Need and Newly Arising Need.
Stage |
Need for Affordable Housing | Number of Households | |
|---|---|---|---|
| 1 | Backlog need existing households | 20,499 | |
| 2 |
minus Cases where in-situ solution most appropriate |
8,846 | |
|
minus Moves within the existing housing stock |
3,476 | ||
|
minus Out-migrants |
1,128 | ||

times proportion unable to afford to rent or buy in market |
7,050 x 59.20% | |
| 4 |
plus Backlog of non-households |
55 | |
| 5 |
equals Total Backlog Need (1 - 2) x 3 + 4 |
4,229 |
|
| 6 |
times Quota to progressively reduce backlog |
20% |
|
| 7 |
equals Annual need to reduce backlog 5 x 6 |

| 8 | New household formation (gross) |
497 x 37.70% =188 |
|
| 9 |
times Proportion unable to buy or rent in market |

| 10 |
plus Ex-institutional population moving into community |
200 x 70.30% =141 |
|
| 11 |
plus Existing households falling into priority need |
45 |
|
| 12 |
plus In-migrant households unable to afford market housing |
3,794 x 27.10% = 1,029 |
|
| 13 |
equals Newly Arising Need (8 x 9) + 10 + 11 + 12 |

On the basis of the Basic Needs Assessment Model, the likely supply of housing is detailed below in Figure 3E.2.
| Stage | Supply of Affordable Housing | Number of Households |
|---|---|---|
| 14 | Supply of social relets | 2,344 |
| 15 |
minus Increased vacancies and units taken out of management |
422 |
| 16 |
plus Committed units of new affordable supply |
- |
| 17 |
equals Total Affordable Supply 14 15 + 16 |
1,922 |
While the supply will satisfy a proportion of the overall need, the model shows that there is a shortfall of 327 affordable homes per year, as noted in figure 3E.3.
