Mangler det fortsatt vikepliktskilt der? Da har vel biler, busser og sykler sørover i Maridalsveien i teorien vikeplikt for sykler som kommer i 30 ned Telthusbakken

Ja interessant eksempel på sammensetningseffekt! Oslo er nesten lavest om vi ser alle husholdningene samlet, men øverst eller nesten øverst *for alle husholdningskategorier* om vi deler i SSBs fire kategorier

Har de publisert noe underlag for hvordan de har regnet ut de 14 milliardene? (Eller bare går de ut i media med et tall?)

Bech Holte slår effektivt ben under sitt eget prosjekt Martin Bech Holte forholder seg til data som fanden leser bibelen. Det er synd, fordi det ødelegger det som kunne vært en konstruktiv debatt om hvordan Norge bør se ut.

Godt fra @martinbholm.bsky.social
Bech Holte forholder seg ikke til faglig kritikk- svarer jo aldri på den. Men vet likevel best ved å tegne grafer på frihånd. Det kunne jo vært fristende å stemple han som er sjarlatan.

Jeg har skrevet om sløseridebatt, offentlig pengebruk og om å prioritere velferd. Det er ikke sløsing å bruke penger på velferd, det er en prioritering. Og skal vi beholde velferdsstaten i fremtiden må vi sannsynligvis regne med at den blir dyrere. Les hvorfor her:

Wealth inequality as measured by the Gini coefficient was very high at the beginning of the twentieth century, fell during the post-war period and has increased substantially since the 1980s. There is also a clear pattern if we look at top 1% wealth shares.

Female labor force participation in historical census microdata
By: Jørgen Modalsli

ABSTRACT
How reliable is historical microdata? Understanding historical labor force participation is crucial for assessing long-term trends in economic development and intergenerational mobility. Most existing historical studies are, however, limited to men, and little is known about how reliable quantitative historical sources are when studying labor market outcomes for women.
This paper documents that the measurement of women's economic activity in the 1910 Norwegian population census had a high level of consistency. There is extensive discussion of measurement issues in historical census reports, micro data can reproduce historical census tables with a high degree of accuracy, and other contemporary reports such as industrial censuses and tax statistics confirm the results found in the census. In addition, a double-enumeration feature of the Norwegian census is leveraged to assess consistency between enumerators, finding no indication that precision in the occupational classification of women is any lower than for men. Some potential sources of downward bias are found in the historical census microdata set provided by IPUMS.
Based on the results in this paper, historical census data appears well suited to study economic activity using modern econometric methods, for women as well as men. A slight upward revision of the 39\% female labor force participation in Norway in 1910 might be in order.

Om jeg har forstått regnestykket rett mangler MDG i overkant av 400 stemmer i landet som helhet (basert på tall lastet ned litt tidligere i dag) for å ta det siste utjevningsmandatet fra Høyre. Eller hvis Rødt tar igjen V i Oslo (200 stemmer), blir det ett utjevningsmandat til til overs, som MDG får

Til slutt: Utjevningsmandatene skal jo jevne ut forskjellen mellom hva partiene får i de ulike valgkretsene, og hva de hadde fått om det bare var en valgkrets. Noen partier får flere mandater enn de ville fått om hele landet var en valgkrets. Denne gangen er det AP med 2 ekstra, og FRP med hele 5.

Hva om arealfaktoren var null, altså at antall mandater til hver valgkrets bare kom an på hvor mange som bodde der, ikke hvor mye land og ferskvann de hadde? Overraskende små endringer. FrP hadde fått to mandater mindre, Arbeiderpartiet og MDG ett mandat til hver.

Hva om sperregrensa var 5%, så KrF og MDG kom under? Da hadde de mistet sine henholdsvis fire og tre utjevningsmandater, og disse hadde blitt tildelt H (3), Rødt (1), SP (2) og SV (1). Altså netto ett mandat mer til venstresiden.

Hva om sperregrensa var 4.5%, så KrF kom under? Da hadde KrF mistet de fire utjevningsmandatene, som hadde blitt tildelt H(1), MDG (1), SP (1) og SV (1). Altså netto tre mandater mer til venstresiden.

Her er noen "hva om"-utregninger etter stortingsvalgresultatet 2025. Alt med forbehold om feil, og at resultatene heller ikke er helt klare ennå (foreløpige tall er lastet ned fra valg.no). Mandatfordelingen med disse tallene er altså:

4 panel Calvin and Hobbes comic strip.
Calvin, very anxious: "It's July already! Oh No! Oh No!"

"What happened to June!? Summer vacation is slipping through our fingers like grains of sand!"

"It's going too fast! We've got to hoard our freedom and have more fun! Time rushes on! Help! Help!"

Last panel, Hobbes, looking puzzled: "I don't think I want to be here at the end of August."
Calvin, running away: "AAUGH! It's a half-hour later than it was half an hour ago! Run! Run!"
