How is each price observed?
On the 1st and 15th of every month, for a fixed travel date 30 days ahead, in each area and segment. The median, the low and the high of the sample are published with the sample size n and the season of the travel date.

测量什么
五个序列：按区域和星级的酒店每晚价格、按区域和卧室数的别墅每晚及每月价格、每人一日游价格、按区域和车型的机场接送价格，以及按区域分三档的每日生活预算。每个序列都是一组观测值，而不是单一的「价格」。
固定观测日期
每月 1 日和 15 日观测，针对 30 天后的固定出行日期，因此各月数据点可比。每个数据点都记录季节（旺季：11 月–4 月；淡季：5 月–10 月）。
中位数与样本量
我们公布样本的中位数、低位、高位和样本量 n。观测值少于 5 个的分段标为无数据——宁可留空，也不猜测。
数据来源
公开挂牌价、合作伙伴价格数据和岛上实地核查。每条观测都保存来源名称和网址供我们自行核对，但不对外公布；指数从不转载任何第三方目录。
货币
所有数字以美元计。国家专页上的本币预算按 fx.json 中的汇率换算，页面上注明汇率日期。
历史
月度数据点追加写入 price-history.json，从不改写。序列累积两个及以上数据点后显示走势图。
从不估算的内容
价格不建模、不外推、不用其他区域的数据填补。缺失的数字在被观测到之前一直缺失。
常见问题
Why is a segment shown as "no data"?
Because fewer than 5 observations were available. A small sample is published as no data rather than as a shaky median — null is better than a guess.
What counts as high and low season?
High season is November to April; low season is May to October. The season is recorded from the travel date of the observation, not the date it was taken.
Are missing prices estimated?
No. Prices are never modelled, extrapolated from earlier months or filled from neighbouring areas. A missing number stays missing until it is observed.
How is the price history kept?
Monthly points are appended to the history file and never rewritten; a month is never duplicated for the same series. Sparklines appear once a series has two or more points.
Which currency is used, and how are conversions made?
All figures are in US dollars. Local-currency budgets on the country pages use the exchange rate on file, and the rate date is printed next to every converted figure.
How do I cite or correct a figure?
Every number may be quoted with a link to the page it comes from; the dataset is CC BY 4.0. To correct a figure, send the area, series, what you observed and the date through the contact page — it is re-checked on the next observation run. The first observation of the index is 2026年9月.
