An open border is a border that enables free movement of people between different jurisdictions with limited or no restrictions to movement. A border may be an open border due to intentional legislation allowing free movement of people across the border or a border may be an open border due to lack of adequate enforcement or adequate supervision of the border which allows the free movement of people across the border combined with inadequate detection and inadequate enforcement within the jurisdiction to ensure people have in fact entered through authorized border controls. An open territorial border allows free movement of people between two different countries or between a group of countries. An example: The open border of this is the opening of international borders between different member states of the European Union which has allowed free movement with very few restrictions. An open civic border allows free movement of people within a country between different states or territories. An example of this is the United States where interstate borders are open with very limited restrictions on movement. The term "open borders" applies only to the flow of people, it does not refer to the flow of goods and services. An equivalent concept to open borders in relation for the free flow of goods and services is free trade. Generally where an open borders policy exist so does a free trade policy but the converse is not necessarily true, there are many examples of a free trade policy which is not accompanied by an open borders policy.
Different types of borders
In order to understand the arguments for and against open borders it is necessary to have a basic understanding of the other types of borders available. These are:
A conditionally open border is a border that allows movement of people across the border that meet a special set of conditions. This special set of conditions which limits the application of border controls that would normally otherwise apply could be defined by an international agreement or international law or the special conditions could be defined by a regulation or law of the jurisdiction that the people are claiming the right to enter. Conditionally open borders generally requires a claim to be submitted from the people who are proposing to enter the new jurisdiction stating the case why they meet the special conditions which allows entry into the new jurisdiction. The new jurisdiction may detain the people until their claim is approved for entry into the new jurisdiction or they may release them into the new jurisdiction while their claim is being processed. When ever a conditionally open border is allowed, considerable effort is often required to ensure that border controls do not break down to such an extent that it becomes an open border type situation. An example of a conditionally open border is a border of any country which allows movement of asylum seekers due either to application of the 1951 Refugee Convention or international law which allows people to cross a border to escape a situation where their lives are directly threatened or in significant danger.
A controlled border is a border that allows movement of people between different jurisdictions but places restrictions and sometimes significant restrictions on this movement. This type of border may require a person crossing this border to obtain a visa or in some cases may allow a short period of Visa free travel in the new jurisdiction. A controlled border always has some method of documenting and recording people movements across the border for later tracking and checking compliance with any conditions associated with the Visa or any other border crossing conditions. A controlled border places limitations on what a person crossing the border can do in the new jurisdiction, this is usually manifested in limitations on employment and also it limits the length of time the person can legally remain in the new jurisdiction. A controlled border often requires some type of barrier, such as a river, ocean or fence to ensure that the border controls are not bypassed so that any people wishing to cross the border are directed to authorized border crossing points where any border crossing conditions can be properly monitored. Given the large scale movement of people today for work, holidays, study and other reasons a controlled border also requires internal checks and internal enforcement within the jurisdiction to ensure that any people who have entered the jurisdiction are in fact complying with any border crossing conditions and that they are not overstaying to reside illegally or as an undocumented resident. Most international borders are by legislative intent of the controlled border type. However when there is a lack of adequate internal enforcement or if the borders are land borders, often the border is only controlled on part of the border and other parts of the border may remain open to such an extent that, it may be considered as an open border due to lack of supervision and enforcement.
A closed border is a border that prevents movement of people between different jurisdictions with limited or no exceptions associated with this movement. These borders normally have fences or walls in which any gates or border crossings are closed and if these border gates are opened they generally only allow movement of people in exceptional circumstances. Perhaps the most famous still-extant example of a closed border is the Demilitarized Zone between North Korea and South Korea. The Berlin Wall can also be called a "closed border".
Examples of controlled borders
- United States and Mexico share a controlled border near major population centers at the boundary between these two countries.
- India and Bangladesh share a border with which India is in the process of turning into a controlled border via the completion of a full border fence between the two countries to control the flow of people between the two countries and prevent illegal migration. Large scale illegal Bangladeshi immigration in the past across the open border has entered India creating Bangladeshi slums on the outskirts of many India cities. The Bangladeshi people are expected to soon form the majority of people in India in areas close to the India Bangladeshi border largely as a result of the past and continuing illegal immigration.
- North Korea and South Korea share a militarized border, known as the Korean Demilitarized Zone and has been in operation since the end of the Korean War in July 1953 when the Korean Armistice Agreement developed the DMZ near the 38th parallel, when the war started. It's meant to keep North Koreans from invading the south and has many landmines and such located in the strip of land. Many North Koreans attempt to cross the border every year, along with the border with China. Even then, only a handful have been able to defect to the South by de-activating the electric fences.
Arguments for open borders
- Open borders advocates argue that free migration is the most effective way to reduce world poverty. Migrants from developing countries can earn higher wages after moving to a more developed country, usually lifting them from 'developing world poverty' to 'developed world poverty'. They also send remittances to relatives in their home country, the glow flow of remittances being estimated to be around three times the global foreign aid spending reported by the OECD.
- A literature summary by economist Michael Clemens leads to an estimate that open borders would result in an increase in GWP (gross world product) of 67-147%, with a median estimate of a doubling of world GDP.
- From a human rights perspective, free migration may be seen to complement Article 13 of the Universal Declaration on Human Rights: (1) Everyone has the right to freedom of movement and residence within the borders of each state. (2) Everyone has the right to leave any country, including his own, and to return to his country.
- American bioethicist Jacob M. Appel has argued that "treating human beings differently, simply because they were born on the opposite side of a national boundary," is inherently unethical. According to Appel, such "birthrights" are only defensible if they serve "useful and meaningful social purposes" (such as inheritance rights, which encourage mothers and fathers to work and save for their children), but the "birthright of nationality" does not do so. Economist and writer Philippe Legrain argues that the countries of the world need migration to help global trade and reduce the occurrence of regional wars.
It has been proposed that borders between the North American Free Trade Agreement (NAFTA) countries be opened. If goods and services and corporations can cross international boundaries without restraint, it is argued, then it does not make sense to impose such extreme restraints on the flow of people who work to make those goods and services.
An extensive reading list of pro-open borders arguments is available on the website Open Borders: The Case, a website advocating and discussing open borders. The authors referenced include Bryan Caplan, Alex Tabarrok, Michael Clemens, Lant Pritchett, Joseph Carens, and many others.
Arguments against open borders
Controlled borders restrict migration by non-citizens. Several arguments for controlled borders and against open borders are as follows:
- That controlled borders encourage responsible policies in relation to population and birth rates for countries by preventing high population and high birth rate countries from disgorging their people onto other low population and low birth rate countries.  However it could be countered that allowing migrants to move to countries where they have better access to contraceptives will actually decrease world population.
- That open borders can be a threat to security and public safety. The threats to security and public safety can sometimes manifest themselves many decades after the initial immigration.
- That large scale migration across open borders can result in demographic changes that can result in demographic shifts that change a country's political power structures in favor of the new demographic and against the existing people of a region or country.
- That open borders can lead to infrastructure deficit in a country. This occurs when large scale migration occurs but the infrastructure to support that migration does not get built.

- India and Pakistan share a border that is almost closed due to the hostilities between these two countries.The border is only open at Wagha.
- Ukraine and Transnistria.
- Algeria and Morocco. Border completely closed since 1994.
