costs for migrant workers who send money back to their friends and families in their country of origin. In light of this, various G8 government developmental organizations, such as the UK government's Department for International Development (DFID) and USAID began to look into ways in which the cost of remitting money could be lowered. In September 2008, the World Bank established the first international database of remittance prices. The Remittance Prices Worldwide Database provides data on sending and receiving remittances for over 200 "country corridors" worldwide. The "corridors" examined include remittance flows from 32 major sending countries to 89 receiving countries, which account for more than 60% of total remittances to developing countries. The resulting publication of the Remittance Prices Worldwide Database serves four major purposes: benchmarking improvements, allowing comparisons across countries, supporting consumers’ choices, and putting pressure on service providers to improve their services. At the July 2009 summit in L'Aquila, Italy, G8 heads of government and states endorsed the objective of reducing the cost of remittance services by five percentage points in five years. To drive down costs, the World Bank has begun certifying regional and national databases that use a consistent methodology to compare the cost of sending remittances. At the G20 2011 Summit in Cannes, Bill Gates stated that, "If the transaction costs on remittances worldwide were cut from where they are today at around 10% to an average of 5%…it would unlock $15bn a year in poor countries." A number of low-cost online services have emerged with the objective of lowering the cost of money transfers to developing and emerging economies. There are also a number of comparison sites when it comes to remittance which breaks down the costs of sending money overseas. The World Bank stated that remittance to low- and middle-income countries reached $529 billion in 2018, which was a record high. Dynamics Emergencies During disasters or emergencies, remittances can be a vital source of income for people whose other forms of livelihood may have been destroyed by conflict or natural disaster. According to the Overseas Development Institute, this is being increasingly recognized as important by aid actors who are considering better ways of supporting people in emergency responses. An illustrative example can be Armenia, that had experienced a devastating earthquake in Spitak on December 7, 1988, when the Karabakh conflict had already started. About 45,000 people have died, while 500,000 became homeless.
