Growth of population statistics<strong>Cohort</strong> <strong>mortality</strong> <strong>in</strong> <strong>Sweden</strong>arithmetic, <strong>in</strong>terest focused among other th<strong>in</strong>gs on the constructionof <strong>mortality</strong> tables as a basis for life <strong>in</strong>surance and life annuitycalculation (Luther 1993, page 17). Even the exist<strong>in</strong>g mercantilism atthe time emphasised the importance of know<strong>in</strong>g the population sizeof the county. A large population was synonymous with wealth andpower. Influences from abroad also aroused <strong>in</strong>terest <strong>in</strong> populationstatistics for <strong>Sweden</strong>. However, the first attempts to compilepopulation statistics beg<strong>in</strong>n<strong>in</strong>g <strong>in</strong> 1721 were not so successful, andthe compilations were never complete.A more well thought-out compilation of population statistics began<strong>in</strong> 1749 with what was known as Tabellverket, which was a set ofpr<strong>in</strong>ted tables. The priests were ordered to annually fill <strong>in</strong> thesetables , based on the <strong>in</strong>formation <strong>in</strong> the church books. Thecompilation of statistics were highly de-centralised. Everycongregation sent <strong>in</strong> their forms to pastoral districts where the<strong>in</strong>formation was summed up and sent on to the deanery"kontraktet" etc. F<strong>in</strong>ally tables could be compiled <strong>in</strong>clud<strong>in</strong>g theentire country. However, all these steps <strong>in</strong>evitably led to a numberof errors. Above all, sometimes congregations or larger areas weremistakenly not <strong>in</strong>cluded <strong>in</strong> the totals. The possibility to centrallycontrol the collected data was very limited. The work to compilestatistics for the entire country more or less stopped for a number ofyears. In 1790 new officials were appo<strong>in</strong>ted to Tabellkommissionen.The secretary was Henric Nicander, astronomer and secretary at theSwedish Academy of Sciences. He began by energetically collect<strong>in</strong>gthe miss<strong>in</strong>g forms and gradually reformed the collection to elim<strong>in</strong>atevarious sources of errors and <strong>in</strong>creased the possibilities to check thestatistics for the commission (Luther 1993, p. 27). Nicander'spersistent work led to a gradual improvement of the quality of thecollected population statistics.Statistics <strong>Sweden</strong> established <strong>in</strong> 1858In 1858 Statistics <strong>Sweden</strong> was established and the collection ofstatistics was re-organised.
