Why do we suppose that globally integrated NGOs tend to engage with each other? First of all, aid of international donors is one of the key recourses for local NGOs from different developing countries. Of course, the size of international aid can vary substantially in different countries; it depends on many conditions. However, even in our empirical case (Kazakhstan – a country, where local NGOs received only modest support from international/foreign donors), more than fifty per cent of examined NGOs received international and/or foreign grants; and these grants were the key source of revenue for 17.66 per cent of them. According Wimmer and Lewis (2010), the group size affect homophily: the bigger the size of a group, the more easily for members will form homophilious in-group ties. This mechanism is termed “availability” (Wimmer & Lewis, 2010).
