<p>Person sampling weight</p>
<div class="i1">The person sampling weight is the inverse of the sampling probability: it is equal to the (estimated) population size of the province divided by the actual sample size. The sampling probabilities and person sample weights vary across provinces, because of two reasons. First, Cairo and Alexandria were sampled by design at a higher rate (8-12%) than the other provinces (1%). Second, certain provinces are assigned higher person weights in the post-sampling phase to account for the non-enumeration of neighboring or geographically similar provinces. Specifically, the weights include the following adjustments:</div><div class="i2">(1) Rosetta in both 1848 and 1868 receives a higher weight to account for the missing Damietta.<br />(2) Al-Qusayr in 1848 is over-weighted to represent the missing Suez.<br />(3) Al-Arish in 1868 is over-weighted to represent al-Qusayr and Suez.<br />(4) Al-Daqahliya and al-Sharqiya in 1868 are over-weighted to represent the other missing Lower Egypt provinces (al-Qalyubiya, al-Gharbiya, al-Minoufiya, al-Buhayra).<br />(5) Giza, Bani-Souayf, Fayuum, and Asyut in 1868 are over-weighted to represent the other missing Upper Egypt provinces (Minya, Girga, Qena, Aswan).</div>
