Who are the foreign born?
The term foreign born refers to people residing in the United States at the time of the census who were not US citizens at birth. The foreign-born population includes naturalized citizens, lawful permanent immigrants, refugees and asylees, legal nonimmigrants (including those on student, work, or other temporary visas), and persons residing in the country without authorization. By comparison, the term native refers to people residing in the United States who were US citizens in one of three categories: 1) people born in one of the 50 states or the District of Columbia; 2) people born in United States Insular Areas such as Puerto Rico or Guam; or 3) people who were born abroad to at least one US citizen parent.

We use the terms immigrants and foreign born interchangeably.

*Note: These are the largest countries of birth reported by the Census Bureau. Some countries are only listed as part of a larger geographic region. For example, those born in Somalia are included only among those born in Eastern Africa. Therefore, a few states may have larger populations of foreign-born persons born in countries not listed individually in census data. "China" refers to China and Hong Kong, but not Taiwan. The 1990 data on the countries of birth reflect geographic boundaries as of 1990.

What Was the Poverty Threshold in 2011?
Whether any family is considered below the poverty threshold depends on the families' total income before taxes, not including any capital gains or noncash benefits, such as food stamps or housing subsidies.

The Census Bureau's poverty threshold varies depending on the number of adults and children in a family. It is adjusted each month to account for inflation. Because respondents filled out the American Community Survey in different months, the poverty threshold applied to each family depends on the month in which the survey was taken.

To give a general idea of poverty levels, as defined by the US Census Bureau, the average poverty threshold for a family of four 2011 was $23,021; for a family of three, $17,916; for a family of two, $14,657; and for an unrelated individual, $11,484. All members of a family are assigned the same poverty status. Poverty thresholds are the same for the whole United States, despite differences in the cost of living across US communities.

Notes:
1. This table describes the entire population of Illinois.
2. For 1990, 2000, and 2011, the total for the region of birth of the foreign born is different from the total foreign born. This is because the 1990 total excludes those who did not report a country of birth and those born at sea, while the 2000 and 2011 totals exclude those born at sea. In 2000 and 2011, individuals who did not report a country of birth were allocated a country (and region) based on various characteristics. Because of this allocation in 2000 and 2011, but not in 1990, the increase for a specific region between 1990 and 2000 is overstated by a small, but unknown, amount.

Notes:
1. The letter N Indicates that a number could not be provided by the Census Bureau because the number of sample cases was too small for this state.
2. Data on the foreign born from Africa and Oceania by period of entry are not available because the number of sample cases was too small for many states.
3. The total for the region of birth of the foreign born is different from the total foreign born. This is because the totals exclude those born at sea.
4. The abbreviation "n.e.c." stands for not elsewhere classified.
5. For Alaska, Maine, Montana, South Dakota, Vermont, and West Virginia the data are from the US Census Bureau's pooled 2009-2011 ACS and for North Dakota and Wyoming the data are from 2007-2011 ACS. For the United States and the rest of the states the data are from 2011 ACS.

Notes:
1. The ACS asks if the person lived in the same house or apartment one year ago. If the respondent indicates that he or she did not live in the same house or apartment one year ago, then the city, town or post office, along with the county, state, and zip code of their residence one year ago, is requested. ACS collects data every month and asks about residence one year earlier without referencing a specific date. These estimates do not include people who lived in Illinois in 2010 and are currently living in Puerto Rico, other US island areas, and foreign countries, or who died between 2010 and 2011. The estimates refer to geographic mobility of persons ages one and older.
2. The letter N Indicates that a number could not be provided by the Census Bureau because the number of sample cases was too small for this state.
