Migration usually occurs out of a need for survival in some way, or a desire for a better standard of living. how can this type of additude, present in migration populations, affect the demographics of a newly settled area?

When an influx of people move to a new city or country, even if it's because of totally legitimate reasons (more jobs, cheaper cost of living, better schools, for example) locals tend to denounce the loss of the old, "real" city. Locals tend to perceive the situation as a threat when "outsiders" come in raising real estate costs, increasing traffic, pollution, etc. in a place that already has an established and "well-functioning" population.

With immigration, you basically have people that the community sees as outsiders causing problems. Often times this perception is an easy trap we fall into when there are obvious characteristics that difference these immigrants to the current population, whether it be language, accents, skin color, or other easily distinguishable attributes.

When a certain area experiences a peak of immigration, it's usually because said area can afford it and the resources are available. The issue more often than not, is discrimination.

Hope this is helpful to you!

from thales, who is often considered the first western philosopher, to the stoics and skeptics, ancient greek philosophy opened the doors to a particular way of thinking that provided the roots for the western intellectual tradition. here, there is often an explicit preference for the life of reason and rational thought. we find proto-scientific explanations of the natural world in the milesian thinkers, and we hear democritus posit atoms—indivisible and invisible units—as the basic stuff of all matter. with socrates comes a sustained inquiry into ethical matters—an orientation towards human living and the best life for human beings. with plato comes one of the most creative and flexible ways of doing philosophy, which some have since attempted to imitate by writing philosophical dialogues covering topics still of interest today in ethics, political thought, metaphysics, and epistemology. plato’s student, aristotle, was one of the most prolific of ancient authors. he wrote treatises on each of these topics, as well as on the investigation of the natural world, including the composition of animals. the hellenists—epicurus, the cynics, the stoics, and the skeptics—developed schools or movements devoted to distinct philosophical lifestyles, each with reason at its foundation.

with this preference for reason came a critique of traditional ways of living, believing, and thinking, which sometimes caused political trouble for the philosophers themselves. xenophanes directly challenged the traditional anthropomorphic depiction of the gods, and socrates was put to death for allegedly inventing new gods and not believing in the gods mandated by the city of athens. after the fall of alexander the great, and because of aristotle’s ties with alexander and his court, aristotle escaped the same fate as socrates by fleeing athens. epicurus, like xenophanes, claimed that the mass of people is impious, since the people conceive of the gods as little more than superhumans, even though human characteristics cannot appropriately be ascribed to the gods. in short, not only did ancient greek philosophy pave the way for the western intellectual tradition, including modern science, but it also shook cultural foundations in its own time.
