Schools run under strict guidelines regarding the quality of the education they provide. In these guidelines, the issue of children per classroom is also included, as it has direct impact on how teachers interact with students and how much they can focus on the needs of an individual. More kids born means that student population will increase, which can lead to two possible situations: either a new school will be built and additional teachers will be hired, which is costly, or the number of students per classroom will rise, adversely affecting the quality of education.
Population loss can also lead to serious implications in the education system. As the number of students becomes smaller and smaller, schools and universities have to reduce their faculties, as a means to tackle declining funds. Especially for institutions requiring tuition fees and who depend primarily on government funding, this scenario can be devastating. The Times Higher Education magazine in the United Kingdom reported studies that suggest that European universities will need to shrink by 2020, or recruit large numbers of overseas students, to adjust to demographic changes.
Diversity within an area's or country's population is not a problem by itself, but it can pose challenges that untrained educators can find difficult to overcome. These challenges include improving the level of language of children coming from different ethnic backgrounds, identifying their talents and helping them adapt to the school environment. Furthermore, educators must be vigilant for unacceptable behavior between students, coming as a result of racial prejudice of any form.
It's not only population changes that affect the education provided, but it happens the other way round as well. For example, the length of education can delay the birth of a child and subsequently drop the average figure of children per family. Teenagers become parents much less frequently than in the past, as they find it necessary to finish high school and continue to college or complete vocational education. In addition, the attractiveness of higher education institutes to foreign students, combined with the ability to seek employment opportunities in the country, can be a factor behind a diverse population.
