The organization of this unprecedented number of activities with a record number of visits was made possible by the regular contributions from IAEA (US$1,703,300), UNESCO (US$373,500) and the Italian Government (US$12,195,000), plus by extraordinary contributions, mainly by the Italian Government, United Nations University, Department for Research Cooperation SAREC of the Swedish International Development Cooperation Agency (SIDA), and European Commission. Numerous other institutions were co-sponsors of the training- for-research activities. !®ft BLAISK STATISTICAL DATA Table 1 and Table 2 show the number of individuals, i.e. visitors, who took part in the training and research activities of ICTP in 1995. The total length of stay is expressed in terms of person-months. Table 1 1995 vs. 1994 VISITORS PERSON-MONTHS TOTAL PERCENTAGE (Dev. vs. total) ; Dev. Adv. Dev. Adv.

The total number of visitors in 1995 reached 4,253 against 3620 of 1994 with an increase of 15%. Out of 4,253, 2,253 (52.97%) were from developing countries against 2,050 of 1994 with an increase of 9%. The total length of stay was 4,733 months (75% accounted for by developing countries). The length of stay by scientists from developing countries increased by 10%. Figures for 1994 and 1995 include the number of scientists present in Italian Laboratories for training and research.
