Withdrawn applications are counted in "decided" but never in a success rate — a withdrawal is usually a redesign, not a refusal. Categories are matched from the application's own wording, so a description mentioning two kinds of work lands in the first that fits.

Asking prices
Are sellers in Jersey asking more than the market has moved?
On the 483 homes for sale that also appear in the sold register, the median asks 2.3% more than the index says its own last sale is now worth. 191 are above the index, 178 below.
What would make this wrong: The index cannot see what has been done to a house between sales. A property extended since it last sold should ask more than the index says, and plenty have been.

Planning
What is hardest to get permission for in Jersey?
Applications for new dwelling are granted 77% of the time, over 68 decisions; signs and shopfronts 95% over 75. Both are high — refusal is rarer here than people assume.

Development
Where is Jersey actually being built?
St Helier accounts for 25% of every new dwelling proposed on the island — 120 of 477.
What would make this wrong: Proposed, not built. One large scheme can carry a whole parish, and a refusal or an abandonment leaves the number standing.
