Scope

Migration is the movement by people from one place to another with the intentions of settling, permanently or temporarily, in a new location. People may migrate as individuals, in family units or in large groups (known as mass migration).^[1] For more clarification on the issue, see this G2G, Immigration vs Emigration.

The migration covered under this scope is often over long distances and includes emigration from one country and immigration to another. This often includes, but is not limited to, topics around colonization, diaspora, economic migrants, or those who are forced to move as a result of conflict, human rights violations, violence, or to escape persecution.

An emigrant leaves from his or her homeland to live in another country.

An immigrant is a person who once resided somewhere else and now lives here (wherever 'here' is).

An easy way to remember what emigrant and immigrant mean is that emigrant and exit both start with 'e', while immigrant and into both start with 'i' (when you emigrate you exit; when you immigrate you come into a country).

For example, a Swedish woman decides to move across the Atlantic Ocean. To herself, and to the country of Sweden, the woman is an emigrant, someone who left Sweden (and went to America). To her new American neighbors, the woman is an immigrant, someone who came into America (and had been born in or living in Sweden). Choosing which term to use depends on perspective: whether she is being referred to by Swedes or by Americans.'

Notes:

1. While internal migration (within one geopolitical entity) is the dominant form globally (e.g. the general trend of movement from rural to urban areas)^[2], it is not covered under the scope of this categorization structure. For internal migration that is important to genealogical research,Category: Regions or Template:Nonmigrating Ancestor should be used.
2. The temporary movement of people for the purpose of travel, tourism, pilgrimages, or for commuting purposes is not regarded as migration, in the absence of an intention to live and settle in the visited places.
3. Nomadic movements are not normally regarded as migrations as there is no intention to settle in the new place and because the movement is generally seasonal.

Principles

Categories are used to group profiles in order to serve a genealogical purpose. Planning on certain category structures is sometimes necessary to keep global categories from becoming useless (too broad or too narrow). If everybody developed categories that they wanted, or that only they could use, we would lose the benefit of having global categories altogether.

For notations, actions or characteristics that would only ever be of personal interest, Personal Categories, Stickers or Templates should be used.

Future needs and development should be considered when creating migration categories. Categories that may fall into multiple categories should be classified as accurately as possible, contain no self-usage (link a category to itself), and not introduce circular references (e.g. being both a parent of and a subcategory of another category).

When the scope of a migration category falls outside of the specified structure herein, or it is unknown how to properly classify the category, it should be discussed with Project:Categorization by asking a question in G2G using the tags - categorization and migration.

The names of all migration categories (especially the landing level migration categories expected to be placed on profiles) should contain enough information to clearly convey the scope and intent of that category, without needing the context of the parent categories it may be nested under.

• [[Category: 1776 Immigration]] is an example of a category name that does not provide any meaningful information to a profile (i.e. where are they Emigrating from, and where are they Immigrating to?).
• [[Category: Migrants from PlaceA to PlaceB]] clearly defines the migration path and no further context is needed to understand the intent of the landing category. Any other relevant details, such as time period, port of entry or vessel, can either be added to the biography, or through the use of other categories (see ??).

Note: Since there are many possible migration categories, it should be noted that not all possible categories have been created, and will only be created when a need arises.

Structure

First Level

The first level is Migration. Since Migration is a top-level category, the parent category is Category:Categories and has been agreed to in G2G discussions, as well as through the collaborative efforts of the Categorization Project.^[3][4]

[[Category:Migration]] L1

The Migration category page should not be modified without prior discussion with the Categorization Project, and no individual profiles should be linked to this category.

---

Second Level

The second level categories contain all country specific categories for both emigration and immigration. The format is Emigrants from Country and Immigrants to Country. Country, Emigrants and Country, Immigrants.

[[Category:Migration]]

[[Category:Emigrants from Country]] L2 [[Category:Country, Emigrants]] L2

[[Category:Immigrants to Country]] L2 [[Category:Country, Immigrants]] L2

No individual profiles should be linked to the second level category.

Content of the category: Category should have CategoryInfoBox Migration template with the following parameters. It will add all necessary parent categories.

For Emigrants from Country 'England, Emigrants' categories	For Immigrants to Country 'England, Immigrants' categories
{{CategoryInfoBox Migration |fromCountry= England }}	{{CategoryInfoBox Migration |toCountry= England }}

---

Third Level

The third level incorporates the details of the administrative entities for a particular Country. The format is Emigrants from AdminEntity and Immigrants to AdminEntity AdminEntity, Emigrants and AdminEntity, Immigrants (based on the parent (second level) category).

Note: Administrative Entities (Admin Entity) are the primary administrative subdivisions of a country. This may also be described as the level in which a country is divided. As an example: The United States uses "States" (regions are geographic only), while countries like England and Sweden use "Counties". In other countries, these may be called "Provinces", "Departments", "Regions", "Prefectures", "Territories", etc.

[[Category:Migration]]

[[Category:Emigrants from Country]] [[Category:Country, Emigrants]]

[[Category:Emigrants from AdminEntity]] L3 [[Category:AdminEntity, Emigrants]] L3

[[Category:Immigrants to Country]] [[Category:Country, Immigrants]]

[[Category:Immigrants to AdminEntity]] L3 [[Category:AdminEntity, Immigrants]] L3

Individual profiles should only be temporarily linked to the third level category when more detailed information is currently unknown.

Content of the category: Category should have CategoryInfoBox Migration template with the following parameters. It will add all necessary parent categories.

For Emigrants from AdminEntity 'Bedfordshire, Emigrants' categories	For Immigrants to AdminEntity 'Bedfordshire, Immigrants'categories
{{CategoryInfoBox Migration |fromCountry= England |fromEntity= Bedfordshire }}	{{CategoryInfoBox Migration |toCountry= England |toEntity= Bedfordshire }}

---

Fourth Level

The fourth level starts to incorporate details of the movement (both from and to), and will include both an Administrative Entity designation and another Country designation. The format is Emigrants from AdminEntity to Country and Immigrants to AdminEntity from Country AdminEntity, Emigrants to Country and AdminEntity, Immigrants from Country.

[[Category:Migration]]

[[Category:Emigrants from Country]] [[Category:Country, Emigrants]]

[[Category:Emigrants from AdminEntity]] [[Category:AdminEntity, Emigrants]]

[[Category:Emigrants from AdminEntity to Country]] L4 [[Category:AdminEntity, Emigrants to Country]] L4

[[Category:Immigrants to Country]] [[Category:Country, Immigrants]]

[[Category:Immigrants to AdminEntity]] [[Category:AdminEntity, Immigrants]]

[[Category:Immigrants to AdminEntity from Country]] L4 [[Category:AdminEntity, Immigrants from Country]] L4

Individual profiles are welcome and accepted at the fourth level. In many cases, only one side of the story is known (i.e. a person left Austria and arrived in New York, United States; or a person left Moravia, Austria and landed in the United States). Once more details are discovered, profiles should be moved to lower-level categories.

Content of the category: Category should have CategoryInfoBox Migration template with the following parameters. It will add all necessary parent categories.

For Emigrants from AdminEntity to Country Bedfordshire, Emigrants to Canada categories	For Immigrants to AdminEntity from Country Bedfordshire, Immigrants from Canada categories
{{CategoryInfoBox Migration |fromCountry= England |fromEntity= Bedfordshire |toCountry= Canada }}	{{CategoryInfoBox Migration |fromCountry= Canada |toCountry= England |toEntity= Bedfordshire }}

---

Fifth Level

The fifth level is the landing category that profiles should strive to fall under. This category level will contain movement from an Administrative Entity to an Administrative Entity. The format will always be Migrants from AdminEntity to AdminEntity, regardless of the parent category that it is nested under (i.e. Emigrants from or Immigrants to Emigrants or Immigrants). The level of detail provided in this level of categorization allows for multi-stream categorization.

[[Category:Migration]]

[[Category:Emigrants from Country]] [[Category:Country, Emigrants]]

[[Category:Emigrants from AdminEntity]] [[Category:AdminEntity, Emigrants]]

[[Category:Emigrants from AdminEntity to Country]] [[Category:AdminEntity, Emigrants to Country]]

[[Category:Migrants from AdminEntity to AdminEntity]] L5

[[Category:Immigrants to Country]] [[Category:Country, Immigrants]]

[[Category:Immigrants to AdminEntity]] [[Category:AdminEntity, Immigrants]]

[[Category:Immigrants to AdminEntity from Country]] [[Category:AdminEntity, Immigrants from Country]]

[[Category:Migrants from AdminEntity to AdminEntity]] L5

Individual profiles should strive to reach this level of categorization.

Content of the category: Category should have CategoryInfoBox Migration template with the following parameters. It will add all necessary parent categories.

For Migrants from AdminEntity to AdminEntity Bedfordshire to Ontario categories
{{CategoryInfoBox Migration |fromCountry= England |fromEntity= Bedfordshire |toCountry= Canada |toEntity= Ontario }}

Multi-Stream Categorization Structures

By following the Categorization Structure displayed in Section 2, a profile can be categorized at the preferred level (Level 5) through two different category streams (Emigration and Immigration). This allows users to follow multiple streams either to, or from a category.

[[Category:Migration]]

[[Category:Emigrants from France]] [[Category:England, Emigrants]]

[[Category:Emigrants from Alsace]] [[Category:Bedfordshire, Emigrants]]

[[Category:Emigrants from Alsace to United States]] [[Category:Bedfordshire, Emigrants to Canada]]

[[Category:Migrants from Bedfordshire to Ontario]]

[[Category:Immigrants to United States]] [[Category:Canada, Immigrants]]

[[Category:Immigrants to New York]] [[Category:Ontario, Immigrants]]

[[Category:Immigrants to New York from France]] [[Category:Ontario, Immigrants from England]]

[[Category:Migrants from Bedfordshire to Ontario]]

Redistribution (Redistricting)

Redistribution is the process by which administrative regions (or geographic areas) are added, removed, or otherwise changed. Redistribution is a form of boundary delimitation that changes political (or geographic) boundaries, usually in response to periodic census results, or through annexation.^[5]

By following the Categorization Structure displayed in Section 2, a profile can be categorized at the preferred level (Level 5) through multiple different streams (i.e. origin and destination). This allows users to follow multiple streams either to, or from a category.

[[Category:Migration]]

[[Category:Emigrants from France]]

[[Category:Emigrants from Alsace]] L3 contains multiple parents (both France and Germany)

[[Category:Emigrants from Alsace to United States]]

[[Category:Migrants from Alsace to New York]]

[[Category:Emigrants from Germany]]

[[Category:Emigrants from Alsace]] L3 contains multiple parents (both France and Germany)

[[Category:Emigrants from Alsace to United States]]

[[Category:Migrants from Alsace to New York]]
