Guam: GDP deflator (base year varies by country)

Key figures

What the numbers say

In 2022, Guam's GDP deflator (base year varies by country) rose 5.5% on 2021 (from 120.88 to 127.49).

Across the 19 yearly changes before that (2003 to 2021), the average change was +2.6% and a typical year strayed about 1.4% from that (the standard deviation). This year's change was 2.1 standard deviations above that average, so it was unusually large compared with the rest of the record.

On record, the biggest yearly rise was 5.5% in 2022. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.

From 2013 to 2022 the straight-line trend is upward, about 2.67 a year. A straight line explains 94% of the movement over 10 observed years.

Worked out from the yearly values above. How the checks work: standard deviation, z-scores and straight-line trends.

A straight-line projection, tested first

Extending that straight line gives about 129.99 for 2025. We show this only because the same method, fitted on earlier years, predicted 2020 to 2022 better than "no change" would have: its average miss was 6.32, against 9.28 for assuming no change. Treat it as a continuation of the recent pattern, not a forecast of events: it cannot see a recession, a policy change or a revision to the data.
