TsukuBlog

Tsukuba City Hall has published a 144-page document with various statistics related to the city. The document is only available in Japanese, but it is a treasure trove of information about the city.

For example, there is a diagram on page 15 (of the pdf file, page 5 of the paper document) that outlines the history of merges that created the city. I knew that Tsukuba was created out of Toyosato Town, Oho Town, Sakura Village, Yatabe Town, Tsukuba Town, and Kukizaki Town, but I did not know that Toyosato was originally Kamigo Town, which itself was originally Kamigo Village.

Page 25 (page 15 of the paper document) lists statistics on the weather from 1998 to 2007, including annual average temperatures, annual high and low temperatures, annual average humidity, annual average wind speed, annual precipitation, and hours of sunlight. It also lists the monthly amounts of the above variables for 2007.

Page 26 (16), says that the area of Tsukuba is 284 km2 with a population of 206,661 (as of October 1, 2007). The population density is 727.5 people per square kilometer. The average household had 2.5 people. There were 5.7 births per day and 3.5 deaths per day. 37.2 people moved into the city per day, and 30.3 people moved out of the city per day. 3.6 couples got married per day and 1.0 couples got divorced per day. As of October 1, 2007, there were 7154 foreigners living in the city, representing 127 countries.
