Series range: 0.205 € – 0.235 € · 75 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: 719–824 period gyros/month

How is it calculated?

Base series · period gyros/month · scenario start 1998

169.01 € ÷ 0.220 € ≈ 768 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 anchor's configured range.

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

Anchors used by the calculation: 1989

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

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 1989 with another year

Period and classic gyro prices, wage and purchasing power, with downloadable image and CSV.

Compare: 1989 → 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.

1989 rank: 5–5 out of 50 years.

Rank one is the highest purchasing power. Published baseline: rank 5.

Minimum–maximum across cases: ≈768–768 per month.

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

1989 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

    0.220 €

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

  2. 2. Model input

    0.220 €

    Single source, rescaled to the reference basket: agoranomiki1989 EUR 0.22 -> EUR 0.22 (100%). Weighted mean EUR 0.22.

  3. 3. Period price in the series

    0.220 €

    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.

    Published: Not established

    Observation period: Not separately recorded

    A 1989 report compares the new beef-patty souvlaki range with the price of gyro or skewer souvlaki. Evidence of a price level, not proof that gyro price regulation ended. National classification is a model choice, not a nationwide sample.

      No specific publication has been mapped to this observation.
