ostotiheys

Ostotiheys is a theoretical metric used in retail analytics to quantify the density of purchase activity within a defined geographic area or time window. It describes how concentrated consumer buying is, after accounting for area size or elapsed time.

Etymology: The term ostotiheys is formed from roots meaning purchase and density in several European languages. There is no single standardized spelling or accepted origin, and the concept is used mainly in academic or industry discussions rather than formal measurement systems.

Calculation: Ostotiheys can be computed in space as the number of transactions per square kilometer, or in time as transactions per day. It may be weighted by basket value, customer dwell time, or product category to reflect economic impact.

Data sources include point-of-sale records, loyalty program data, and anonymized mobile location data. The metric is often mapped to neighborhoods or trading zones to reveal hot spots and patterns of turnover.

Applications: Retail site selection, store clustering, inventory planning, and staffing decisions can benefit from ostotiheys by highlighting where purchase activity concentrates and when it spikes. It is commonly used alongside other metrics such as footfall and conversion rate.

Limitations: Results depend on data quality and spatial granularity. Privacy concerns, seasonality, and unequal basket sizes can distort ostotiheys, so it is typically interpreted in combination with related indicators.
