how many countries reach the targeted threshold of 0.7 of their Gross National Income (GNI) for Official Development Assistance (ODA)?

To answer this question, we would need to follow these steps:

1. Identify the targeted threshold for Official Development Assistance (ODA) which is 0.7% of Gross National Income (GNI).

2. Research and gather data on the GNI and ODA of all countries. This information can be found in databases of international organizations such as the World Bank, the United Nations, or the Organisation for Economic Co-operation and Development (OECD).

3. Calculate the ODA as a percentage of GNI for each country. This can be done by dividing the ODA by the GNI and then multiplying by 100 to get the percentage.

4. Compare the calculated percentages with the targeted threshold of 0.7%.

5. Count the number of countries that meet or exceed this threshold.

Please note that this information is constantly changing as countries' GNIs and ODAs fluctuate. Therefore, the exact number of countries reaching the targeted threshold can vary over time.

As of the last available data from the OECD in 2019, only 5 countries (Denmark, Luxembourg, Norway, Sweden, and the United Kingdom) met or exceeded the 0.7% target.
