Landlocked developing countries in the context of "Developing country"

A developing country is a country with a less-developed industrial base and a lower Human Development Index (HDI) relative to developed countries. However, this definition is not universally agreed upon. There is also no clear agreement on which countries fit this category. The terms low-and middle-income country (LMIC) and newly emerging economy (NEE) are often used interchangeably but they refer only to the economy of the countries. The World Bank classifies the world's economies into four groups, based on gross national income per capita: high-, upper-middle-, lower-middle-, and low-income countries. Least developed countries, landlocked developing countries, and small island developing states are all sub-groupings of developing countries. Countries on the other end of the spectrum are usually referred to as high-income countries or developed countries.

There are controversies over the terms' use, as some feel that it perpetuates an outdated concept of "us" and "them". In 2015, the World Bank declared that the "developing/developed world categorization" had become less relevant and that they would phase out the use of that descriptor. Instead, their reports will present data aggregations for regions and income groups. The term "Global South" is used by some as an alternative term to developing countries.

The United Nations geoscheme is a system that divides 248 countries and territories in the world into six continental regions, 22 geographical subregions, and two intermediary regions. It was devised by the United Nations Statistics Division (UNSD) based on the M49 coding classification. The creators note that "the assignment of countries or areas to specific groupings is for statistical convenience and does not imply any assumption regarding political or other affiliation of countries or territories".

The UNSD geoscheme was created for statistical analysis and consists of macro-geographical regions arranged to the extent possible according to continents. Within each region, smaller geographical subregions and sometimes intermediary regions contain countries and territories. Countries and territories are also grouped non-geographically into selected economic and other sets, such as the landlocked developing countries, the least developed countries, and the Small Island Developing States.
