United States Migration Stats

Background:

Formerly known as the New World, immigration has long been a major aspect of US life. Indeed, it has the largest immigrant population on earth, with 38 million people arriving in the country from abroad. However, the US also has the highest number of new citizenships in the world. In 2000, some 898,000 immigrants became US citizens - 4 times that of the 2nd-placed nation, Canada.

Definitions

  • Asylum Seekers: Thousands of asylum seekers coming into a nation in 2001.
  • Asylum Seekers per million: Thousands of asylum seekers coming into a nation in 2001. Figures expressed per million population for the same year.
  • Asylum seekers acceptance rates > 1990-99: % of asylum seekers accepted between the years 1990 and 1999.
  • Foreign population: Foreign population as % of total population; data for 2000
  • Foreign worker salaries: Workers' remittances and compensation of employees comprise current transfers by migrant workers and wages and salaries earned by nonresident workers. Remittances are classified as current private transfers from migrant workers resident in the host country for more than a year, irrespective of their immigration status, to recipients in their country of origin. Migrants' transfers are defined as the net worth of migrants who are expected to remain in the host country for more than one year that is transferred from one country to another at the time of migration. Compensation of employees is the income of migrants who have lived in the host country for less than a year. Data are in current U.S. dollars."
  • International migrant stock > Total: International migrant stock is the number of people born in a country other than that in which they live. It also includes refugees. The data used to estimate the international migrant stock at a particular time are obtained mainly from population censuses. The estimates are derived from the data on foreign-born population--people who have residence in one country but were born in another country. When data on the foreign-born population are not available, data on foreign population--that is, people who are citizens of a country other than the country in which they reside--are used as estimates. After the breakup of the Soviet Union in 1991 people living in one of the newly independent countries who were born in another were classified as international migrants. Estimates of migrant stock in the newly independent states from 1990 on are based on the 1989 census of the Soviet Union. For countries with information on the international migrant stock for at least two points in time, interpolation or extrapolation was used to estimate the international migrant stock on July 1 of the reference years. For countries with only one observation, estimates for the reference years were derived using rates of change in the migrant stock in the years preceding or following the single observation available. A model was used to estimate migrants for countries that had no data."
  • Net migration: Net migration is the net total of migrants during the period, that is, the total number of immigrants less the annual number of emigrants, including both citizens and noncitizens. Data are five-year estimates. To derive estimates of net migration, the United Nations Population Division takes into account the past migration history of a country or area, the migration policy of a country, and the influx of refugees in recent periods. The data to calculate these official estimates come from a variety of sources, including border statistics, administrative records, surveys, and censuses. When no official estimates can be made because of insufficient data, net migration is derived through the balance equation, which is the difference between overall population growth and the natural increase during the 1990-2000 intercensal period."
  • Net migration > Per capita: Net migration is the net total of migrants during the period, that is, the total number of immigrants less the annual number of emigrants, including both citizens and noncitizens. Data are five-year estimates. To derive estimates of net migration, the United Nations Population Division takes into account the past migration history of a country or area, the migration policy of a country, and the influx of refugees in recent periods. The data to calculate these official estimates come from a variety of sources, including border statistics, administrative records, surveys, and censuses. When no official estimates can be made because of insufficient data, net migration is derived through the balance equation, which is the difference between overall population growth and the natural increase during the 1990-2000 intercensal period." Per capita figures expressed per 1 million population.
  • Net migration rate: The difference between the number of persons entering and leaving a country during the year per 1,000 persons (based on midyear population). An excess of persons entering the country is referred to as net immigration (e.g., 3.56 migrants/1,000 population); an excess of persons leaving the country as net emigration (e.g., -9.26 migrants/1,000 population). The net migration rate indicates the contribution of migration to the overall level of population change. High levels of migration can cause problems such as increasing unemployment and potential ethnic strife (if people are coming in) or a reduction in the labor force, perhaps in certain key sectors (if people are leaving).
  • New citizenships: Thousands of people who acquired nationality in 2000. Statistics cover all means of acquiring the nationality of a country, except where otherwise indicated. These include standard naturalisation procedures subject to age, residency, etc. criteria, as well as situations where nationality is acquired through a declaration or by option (following marriage, adoption, or other situations related to residency or descent), recovery of former nationality and other special means of acquiring the nationality of a country. For more details on sources, refer to the notes at the end of the OECD Annex.
  • New citizenships per million: Thousands of people who acquired nationality in 2000. Statistics cover all means of acquiring the nationality of a country, except where otherwise indicated. These include standard naturalisation procedures subject to age, residency, etc. criteria, as well as situations where nationality is acquired through a declaration or by option (following marriage, adoption, or other situations related to residency or descent), recovery of former nationality and other special means of acquiring the nationality of a country. For more details on sources, refer to the notes at the end of the OECD Annex. Figures expressed per million population for the same year.
  • Refugee population by country or territory of asylum: Refugees are people who are recognized as refugees under the 1951 Convention Relating to the Status of Refugees or its 1967 Protocol, the 1969 Organisation of African Unity Convention Governing the Specific Aspects of Refugee Problems in Africa, people recognized as refugees in accordance with the UNHCR statute, people granted refugee-like humanitarian status, and people provided temporary protection. Asylum seekers--people who have applied for asylum or refugee status and who have not yet received a decision or who are registered as asylum seekers--are excluded. Palestinian refugees are people (and their descendants) whose residence was Palestine between June 1946 and May 1948 and who lost their homes and means of livelihood as a result of the 1948 Arab-Israeli conflict. Country of asylum is the country where an asylum claim was filed and granted."
