Suitability Analysis Constraints Opportuni\es Beijing

Ques&on: Suitability Analysis for Migrant Schools in Beijing Given migrant children’s lack of access to public schools and need by Kan Liu Sources: Migrant school list (1kg.org), Harvard GIS (worldmap.harvard.edu/chinamap), OSM (download.geofabrik.de)
for special schools, where are the op&mal zones for establising migrant schools in Beijing? Solu&on: Beijing Migra&on and Percent Change in # of Primary schools Iden&fy constraint and opportunity factors related to migrant schools in order to create a suitability analysis Findings: China Sources: China City Sta&s&cal Yearbook 2003, 2011
Source: Educa&onal Sta&s&cal Yearbook of China 2011; 2010; 1985 Background: China’s rural-‐to-‐urban migra&on has reached 240 million Suitable zones are concentrated in Beijing’s center (inside the 5th ring road) due to easy access to public transit, which is in opposi&on to the distribu&on paHern of exis&ng migrant schools Limita&ons: Problem: Migrant children cannot aHend public schools due to the Hukou system Solu&on: Migrant schools Constraints IDW 1.  Due to &me and data constraints, many relevant factors are not included. Ideally, I should include natural factors such as slope and earthquake zones and, more importantly, socio-‐economic factors such as land use, rental prices, migrant popula&on census counts, and current migrant schools’ characteris&cs. 2.  My ﬁndings do not explain why current exis&ng migrant schools are located outside the 5th ring road (outskirts of Beijing). My analysis does not take into considera&on either land costs or the legal stauts of migrant schools. 3.  Data gathered from Google and OpenStreetMap are not comprehensive and may not accurately reﬂect up-‐to-‐date informa&on.

Result analysis: Darker green zones (concentrated in the urban center) are suitable for establishing migrant schools, whereas darker brown zones are less suitable for migrant schools.
