Migra­tion refers to the per­ma­nent move­ment of a popu­la­tion from one area to anot­her. People have always moved - wit­hout them, the earth would not have been comple­te­ly inha­bi­ted. Popu­la­tion moves both wit­hin sta­tes and across borders. 

It is impos­sible to dis­mant­le the many causes of migra­tion, but it is simply bro­ken down that the­re are fac­tors behind migra­tion from the region of depar­tu­re and, con­sequent­ly, the­re are temp­ting fac­tors on the region of ent­ry. Under­lying idea behind migra­tion is often the idea, that the tar­get region has more oppor­tu­ni­ties to impro­ve the qua­li­ty of life. This is done, for example, through the workplace or stu­dies. Social fac­tors also have a sig­ni­ficant impact on an individual’s migra­tion deci­sions. It is often felt that the­re is the grea­test poten­tial for impro­ving the qua­li­ty of life in cities whe­re the stron­gest migra­tion stream has long been directed.

Urba­niza­tion is a glo­bal­ly sig­ni­ficant phe­no­me­non. Urba­niza­tion refers to a social process in which the popu­la­tion living in cities is growing. It is pro­jec­ted that glo­bal­ly, two-thirds of all people will live in cities by 2030. The degree of urba­niza­tion in Fin­land is esti­ma­ted to be as high as 86%. Urba­niza­tion also has its down­si­des: in deve­lo­ping count­ries, for example, infra­struc­tu­re can­not car­ry a migra­ting popu­la­tion, ins­tead slums are built around the cities. In Fin­land, for example, urba­niza­tion is causing rural areas deser­ti­fica­tion. For indi­vi­duals, urba­niza­tion causes housing traps in the housing mar­ket, which we have writ­ten about ear­lier in our blog. It is esti­ma­ted that in 20 years the­re will be only three growing urban areas in Fin­land: Hel­sin­ki, Tur­ku and Tampere. 

Migra­tion can also be caused, for example, by unin­ha­bi­table areas in for­mer resi­den­tial areas, which can be the result of, for example, sud­den natu­ral disas­ters. Such sud­den chan­ges, at worst, destroy the homes of thousands of people in an ins­tant. In such a situa­tion, it must be pos­sible to pro­duce affor­dable housing quickly. Tri­fa­mi 3D tech­no­lo­gy would be an excel­lent addi­tion to meet such demand, and in some cases the solu­tion could even alle­via­te migra­tion pres­su­re. In any case, the­re will always be migra­tion and it is impor­tant to be able to pro­duce eco­lo­gical and affor­dable housing in the migra­tion areas. 

For this problem too, the 3D prin­ting of conc­re­te is the solu­tion for the future.
