Beds, occupancy, length of stay and day-trippers follow rounded official statistics. Growth rates and the market cycle reflect each region's recent behaviour: growth slows as occupancy nears its ceiling and oscillates with the cycle instead of rising linearly. The 0–100 indices are comparable teaching estimates.
