Hamburger Bun Prices Raw Dataset (2026)

[image]

Analyze 24,551 unaggregated product-level listed retail prices for hamburger buns across 12 U.S. ZIP markets from July 13 through August 10, 2026. The single analysis-ready CSV preserves titles, dates, geography, package quantities, listed prices, and a source-neutral comparable-price field.

What “raw” means here: unaggregated product-level observations after scope and safety filtering. The file includes derived normalization fields; it is not untouched acquisition data.

A result worth investigating

59.7% of rows expose a quantity-cleaning challenge. Only 9,900 of 24,551 rows (40.3%) have a compatible resolved bun count for the 10 buns comparison. The unresolved rows remain in the file with their listed prices and a blank comparable-price field, making missingness an explicit analysis surface.

What one row represents

One row is one quality-filtered product-title, ZIP-market, date, package-quantity, and listed-price observation. It is not a sale, order, demand, inventory, market-share, or consumer record. Distinct offers may share a title, ZIP, and date; exact duplicate public rows are removed.

Comparable-price method

The fixed comparison target is 10 buns. Compatible count units normalize to 10 buns; unresolved pack counts remain blank. Original package fields remain available for audit.

Project ideas

  • —Analyze ten-bun package-equivalent prices
  • —Track matched product titles through time
  • —Compare selected ZIP markets
  • —Build a reproducible retail-price dashboard
  • —Run reproducible EDA and missing-value analysis

Quick start with Pandas

python
import pandas as pd

df = pd.read_csv(
    "costinflation-hamburger-bun-retail-prices-raw-2026-07-13-to-2026-08-10.csv",
    dtype={"geography_id": "string"},
)
comparable = df.dropna(subset=["normalized_price_amount"]).copy()
print(comparable["normalized_price_amount"].describe())

Quality and limitations

  • —All 348 expected date × ZIP-market combinations are present.
  • —Exact duplicate public rows: 0. The preparation pass removed 37 byte-identical input repeats.
  • —Scope review excluded 0 definite out-of-scope or unsafe titles representing 0 input rows.
  • —Product titles are descriptive text, not stable public product identifiers.
  • —ZIP labels describe selected markets, not citywide estimates; the panel is not nationally representative.
  • —Availability and title wording can change unmatched aggregates through assortment change.
  • —Shipping, tax, redeemed promotions, purchases, and product performance are outside the dataset.
