Industrious Revolution

First, professor Hayami generated household micro database called Basic Data Seat, with religious inquisition registration (native:宗門改帳). [3]Next, based on this database, he observed about 900 villages in Nobi region and exploited the following fact.[4] Number of livestocks in these villages decreased gradually from late 17th century to 19th century, while population and production increased or constant. People's life expectancy was also pointed out to be improved over 10 years[5]. These facts implies that the quantity of human labor input without livestocks would have increased with aggregate output constant, which he named Industrious Revolution[6]. This is Japanese pioneering research to describe population dynamics before Industrial Revolution with statistical methods[7] .

gollark: Including houses.
gollark: So, if you construct giant bubbles of sealed lightweight resin or something in space containing vacuums, then deorbit them carefully, you can attack things to them and they float.
gollark: Too bad.
gollark: But vacuum pumps are also expensive. But there's free vacuum in space.
gollark: So the obvious solution is of course VACUUM, which has the MAXIMUM buoyancy.
