Dear Census and Statistics Department,

I am writing to request operational statistics regarding response and data collection channels for all Population Census and Population By-census. I would like to request these figures for all available years in departmental records (from the earliest date such administrative breakdowns were compiled up to the 2026 interim data).

For each census/by-census year available, I would appreciate your provision of the following–

1. The total number of households targeted or sampled for the data collection exercise (including Long Form and Short Form splits, where applicable)
2. The total number of households that self-responded, broken down by whatever historical channels were tracked during that specific cycle (e.g., postal paper returns, telephone interviews, online e-Forms, etc.)
3. The total number of households that required face-to-face enumeration by census field officers due to non-response.

I would really appreciate if the data was presented in any electronic (e.g. Excel/PDF) format rather than tabular format as I cannot read this. Thank you very much for your attention to this matter.

Yours faithfully,

James A. Wilson
