Each award is placed by its delivery postcode, or by the recipient's registered postcode when no delivery postcode is given. Many of the second kind are local organisations whose delivery location simply wasn't recorded, but they also include national organisations headquartered here, which is why city-centre seats can show large totals for money that is actually spent elsewhere.
