Passage: From 2002–11, there has been negative net migration, with an annual negative 109 net immigrants from 2006–11. In 2009 there were 1,820 arrivals and 1,736 departures, for a positive rate of 84 immigrants. This was the first time since collecting data in 2002, there was a positive rate. Data on arrivals and departures collected by the Nauruan Customs and Immigration Office is not available, so specific immigration data is unavailable. As of the 2011 census, 57% of the population over 15 years old were legally or de facto married, 35% were never married, while 7% were either widowed, separated, or divorced. There are 1,647 households in Nauru, making an average household size of 6.0 persons per household.
How many years after 2002 was there a positive rate? How many years was immigration and negattive 109 net immigrants? How much of the population over 15 years old were never married as of 2011? In the first year that there was a positive rate of immigrants, how many left? Were more people legally/de facto married or never married as of the 2011 census? Were there more arrivals or departures in 2009? Which did the population have less of, those never married or those over 15 years old were legally or de facto married? Which were there more of, arrivals or departures?
