The UNICEF estimates that an average of 353,000 babies are born each day around the world. The crude birth rate is 18.9 births per 1,000 population or 255 births globally per minute or 4.3 births every second (as of Dec. 2013 estimate).
We estimate that approximately 1,900 new late infantile babies are born each year (60 in the US and 170 in Europe) and there are approximately 41,000 people alive at any given time with all forms of MLD worldwide.
