Estimates of the completeness of the DSS and SSH data sources
| Observed Data | Capture-Recapture Estimates | |||||
|---|---|---|---|---|---|---|
| Only in SSH Data (“additions”) (A) |
Only in HDSS Sibship Lists (“omissions”) (B) |
In both data sets (“matches”) (C) |
Number Missed by Both Sourcesa (D) |

| All Sistersd | 91 (9.2) | 107 (10.8) | 795 (80.0) | 12 | 89.8 | 88.2 |
| Sisters Under Age 15 | 67 (22.6) | 43 (14.5) | 186 (62.9) | 15 | 73.6 | 81.3 |
| Adult Sisters (≥15) | 26 (3.4) | 64 (8.4) | 675 (88.2) | 2 | 96.3 | 91.3 |
| Sisters deceased at adult ages | 3 (1.0) | 28 (8.6) | 295 (90.4) | <1 | 99.1 | 91.4 |
a
This is calculated as (A × B) / C.
b
This is calculated as (B + C) / (A + B + C + D).
c
This is calculated as (A + C) / (A + B + C + D).
d
These tabulations ignore discrepancies in reports of vital status and age at death/current age between SSH and HDSS data. For example, one sister was reported as deceased by the SSH respondent but was recorded as alive in the HDSS data set: she is counted in column C here, not in column A.
