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

The National Association of Realtors monthly housing indicators are based on a representative sample of local boards and multiple listing services. Sales volume, inventory, and price levels for existing homes are measured for the US in aggregate and by census region. Existing homes, unlike new homes, are homes that are owned and occupied before coming onto the market.

Inventory indicates the number of properties marked as "active" on the market or those pending sales. When a seller lists a property, it becomes counted as inventory.

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