Males are usually born in excess of females and the ratio of male births to female births is conventionally referred to as M/F. Many factors, including stress, privation and natural disasters are associated with a lowering of M/F. Malta has a North-South divide, with a more affluent North as opposed to a more industrialised and less prosperous South. This study was carried out in order to ascertain whether regional economic differences influenced M/F in Malta.
Births by gender, year of birth and locality from 1999 to 2013 were subdivided into ten regions in a geographic distribution devised by the Department of Health Information and Research. Regions were also amalgamated into two groups of five which represented North-West and South-East Malta. The island of Gozo was considered separately.
There were no statistically significant differences in M/F between the ten regions nor between North-West, South-East and Gozo regions. There were no significant secular trends in M/F in these regions.
M/F declines under adverse environmental factors (including economic stress) but despite the overall poorer economic circumstances in the South of the Island, this study failed to show a significant difference in M/F by region. This may be due at least in part to the relatively small numbers involved. Alternatively, the purported socio-economic differences may not have been sufficiently large so as to skew M/F to statistically significant levels.peer-reviewe
