Seasonality (Average by Month)

What am I looking at?

What it shows: the average level of the series for each calendar month (Jan…Dec) across the full history.

Computation: for each month m, take the mean of all observations whose calendar month = m (all years equally weighted).
Interpretation:
- Not seasonally adjusted (NSA): clear recurring peaks/troughs by month.
- Seasonally adjusted (SA): should be fairly flat (seasonality already removed).
Caveats: uses raw levels, so long-run trend can dominate; best for monthly series. For a relative view, consider a seasonal index (month_mean ÷ overall_mean − 1) or limit to the last N years.

What this measures & how to read it

Copyright, 2016, National Association of Realtors. Reprinted with permission. Per the agreement with the source, data in FRED are available for the prior 13 months.

Measures the degree to which a typical family can afford the monthly mortgage payments on a typical home.

Value of 100 means that a family with the median income has exactly enough income to qualify for a mortgage on a median-priced home. An index above 100 signifies that family earning the median income has more than enough income to qualify for a mortgage loan on a median-priced home, assuming a 20 percent down payment. This index is calculated for fixed mortgages.

Tip: focus on multi-month trends to reduce noise from seasonality, one-off shocks, and revisions.
