| Wealth quintile | Total TLU | Percent of total TLU | Mean per adult equivalent TLU |
|---|---|---|---|
| Q1 | 415 | 51.09 | 5.37 |
| Q2 | 195 | 24.00 | 2.05 |
| Q3 | 116 | 14.25 | 1.19 |

Notes: Wealth quintiles calculated by ranking all households by household TLU with cutpoints at 20% intervals. TLU is tropical livestock units; 1 cow=1 TLU; 1 sheep=0.12 TLU; 1 goat=0.13 TLU. Per adult equivalent converts as follows: adult male=1; adult female=0.86; children 11–17=0.96; 6–10=0.85; 0–5=0.52.
