opptelling

Opptelling is the process of determining a total by counting individual units or events. In Norwegian usage it covers both simple arithmetic counting and the aggregation of data in more formal contexts, such as statistics, inventory management, and elections. The noun opptelling is formed from the verb telle (to count) with the prefix opp-, indicating a result or completion of counting.

In mathematics and statistics, opptelling refers to enumerating occurrences, tallying values, and, more generally, compiling data by counting. In business and logistics, it describes stocktaking and counting goods to determine inventory levels. In elections and referendums, opptelling denotes the counting of ballots and the reporting of vote totals; depending on jurisdiction, it may be followed by recounts or audits to verify accuracy.

The process typically involves recording individual counts, summing totals, and validating results against records to identify discrepancies. Tools range from manual tally counters and paper tallies to computerized systems that directly aggregate data and produce reports. Transparency and auditability are often emphasized, especially in high-stakes contexts like elections.
