Data was gathered from The World Bank here: datahelpdesk.worldbank.org/knowledgebase/articles/906519
To visualise this I used: mapchart.net/world.html
Info about this map: the * for country is due to The World Bank using the term country interchangeably with economy and does not imply political independence but refers to any territory for which authorities report separate social or economic statistics.
Not represented in this map:
Lower-Middle Income: Cabo Verde, Comoros, Kiribati, Micronesia Fed. Sts., São Tomé and Principe, Solomon Islands, Vanuatu
Upper-Middle Income: American Samoa, Dominica, Fiji, Grenada, Maldives, Marshall Islands, Mauritius, Nauru, Samoa, St. Lucia, St. Vincent and the Grenadines, Tonga, Tuvalu
High Income: Antigua and Barbuda, Aruba, The Bahamas, Barbados, Bermuda, British Virgin Islands, Cayman Islands, Channel Islands, Curaçao, Faroe Islands, French Polynesia, Gibraltar, Guam, Isle of Man, Liechtenstein, Macao, New Caledonia, Northern Mariana Islands, Palau, San Marino, Seychelles, Sint Maarten (Dutch part), St Kitts & Nevis, St. Martin (French part), Turks and Caicos Islands, Virgin Islands
Note: French Guiana has been listed as No data due to not being present in The World Bank data, however I belive that it reports its economy alongside France, in which case can be seen as High Income
