Series range: 0.021 € – 0.045 € · 11 GRD

The wrap of the period, at the historical series price. The price may be documented or estimated, as explained in the year’s sources.

Range from price bounds: 499–1,069 period gyros/month

How is it calculated?

Base series · period gyros/month · scenario start 1998

22.44 € ÷ 0.033 € ≈ 680 period gyros/month

After contributions, before income tax. Annual income divided by 12, using 14 payments throughout the series. Wage and contributions are twelve-month means. Purchasing power in period gyros.

The quotient is rounded to a whole number.

Only the price varies within its published bounds. Wage and composition stay fixed. This is neither a total uncertainty range nor a statistical confidence interval. Bounds come from the model's selected percentage band.

Price anchor

The series uses an anchor for this year. The entry may include rescaling or time weighting. It does not certify a national sample.

Regulated price of 10 GRD for a doner wrap with pita and seasoning (9 GRD with bread), a ceiling rather than a free price. Rescaled to an estimated market price with a 1.11 regulation factor.

Anchors used by the calculation: 1978

The era view applies no meat-weight or composition rescaling to a classic product.

What do the sources support?

Categories describe how the price enters the model. They do not certify original-source verification, representative sampling or historical product composition.

Historical meat weights and changes in composition are model assumptions, not a series of market measurements. The assumed peak and decline in portion size need verification. The present-day weight defines the reference product. The era price refers to the wrap sold at the time; the classic price and weight-adjusted index depend on these assumptions.

Compare: 1978 → 2026

Which findings hold up?

We combine 2 wage bases, 4 historical-price choices and 7 composition specifications across 50 completed years, 1976–2025.

Counts are not probabilities. Payroll reconstruction remains under review. Portion scenarios are not measurements; geography and sale channel stay fixed.

Period gyros

8 distinct combinations. Portion assumptions do not affect this measure.

1978 rank: 10–10 out of 50 years.

Rank one is the highest purchasing power. Published baseline: rank 10.

Minimum–maximum across cases: ≈680–680 per month.

Extremes of the selected specifications, not an uncertainty interval. Ranks precede rounding of displayed counts.

1978 remains above 1976 in every selected case.

Where this figure comes from

Price anchor. The series uses an anchor for this year. The entry may include rescaling or time weighting. It does not certify a national sample.

The era price is an input or calculation in the series. Comparison in classic gyros adds assumptions about weight and composition.

Detailed evidence and calculation

What is supported for this year

We examine price, date, place and product composition separately. Evidence for the price does not establish historical meat weights.

The detailed year review is pending. This does not mean no sources exist.

Price
Sources and the calculation are shown below. A separate review of these dimensions has not yet been completed for this year.
Date
A separate check of publication date and observation date has not yet been completed here.
Geography
A separate review of geographical coverage and adjustments has not yet been completed here.
Composition
Historical meat weights and changes in composition are model assumptions, not a series of market measurements. The assumed peak and decline in portion size need verification. The present-day weight defines the reference product. The era price refers to the wrap sold at the time; the classic price and weight-adjusted index depend on these assumptions.

From source to series price

A source entry is not always the final price. These are the inputs retained by the model, without implying fresh verification of the original.

  1. 1. Amount before rescaling

    0.029 €

    The recorded original amount before any rescaling. It may be a regulated ceiling or composite input, not an individual purchase.

  2. 2. Model input

    0.033 €

    Regulated price of 10 GRD for a doner wrap with pita and seasoning (9 GRD with bread), a ceiling rather than a free price. Rescaled to an estimated market price with a 1.11 regulation factor.

  3. 3. Period price in the series

    0.033 €

    The final price used for period purchasing power. Classic composition rescaling is a separate subsequent step.

In some years an anchor constrains the range rather than replacing the calculated price. Historical amounts use the fixed drachma-to-euro conversion, without inflation adjustment.

What the contemporary press reported

Messinia: the preceding regulated gyro-pita price

Σημαία ·

Issue 20657, p. 1, right. Market Order 9, 24 June 1978, EM 2571, articles 2–5.

Effective from:

Gyro or patty with pita and seasoning, regulated price
10 GRD
Gyro or patty with bread, regulated price
9 GRD
Pork skewer with pita, regulated price
8.5 GRD
Cooked-gyro specification
37–40 g

The order separates gyro from pork skewers, and bread from pita, for standing customers. It applies in Messinia the day after publication, giving 26 June. The January 1979 order explicitly references it and replaces its pricing article. Continuity until then is a reconstruction of the regulatory sequence, not daily market measurement.

Shop prices are needed to test compliance with the regulated schedule and its distance from actual market prices.
