London Shawarma Prices Show Little Correlation with Property £/m²
19 chicken-shawarma prices across 18 London postcode districts, each joined to HouseMetric's median residential sold price per m² for that district (generally the latest 24 months). District-level Pearson r = 0.106 and Spearman rho = 0.145; restaurant-level r = 0.098 and rho = 0.154. All four values sit near zero: at most a negligible positive association, not evidence that pricier property areas charge more for shawarma.

How to read this result
Correlation here is descriptive, not causal, and the sample is exploratory. This expanded 18-district result supersedes the earlier two-point r = 1.00, which was not interpretable. Known limitations:
- property figures consistently use the postcode-district median residential sold price per m², generally over the latest 24 months — commercial rents, the more plausible cost driver for a takeaway, are not tested;
- shawarma menus carry mixed or missing dates, including one 2022 review price and one 2024 observation, and one observation is a Reddit report;
- listed items differ in size (small, medium, large) and channel (delivery platform versus in-store);
- 17 of 18 districts rest on a single restaurant, so each district mean is fragile.

Method: 19 restaurant-level joins across 18 London postcode districts, pairing each chicken-shawarma listing with HouseMetric's postcode-district median residential sold price per m², generally over the latest 24 months. District means average shawarma prices within a district (only SE1 has two restaurants). District-level Pearson r = 0.106, Spearman rho = 0.145; restaurant-level r = 0.098, rho = 0.154. Menu prices mix delivery and in-store channels, sizes, and dates (2022–2026, mostly undated); one observation is Reddit-sourced. Correlation is descriptive, not causal, and residential sale price is a proxy — commercial rents were not tested. All rows shown; the trend line is an ordinary least-squares fit over the 18 district points, drawn for orientation only. Assembled from the expanded join that supersedes the earlier uninterpretable two-point result.
