We studied demography from 1980 to 1987 and death causes in the population of the USSL 12 of LombardY in 1986-1987. The USSL includes 63,255 inhabitants on a surface of 60 km2. BIRTH and mortality rates. We collected data about births, deaths, immigration and emigration in every municipality of USSL 12 from 1980 to 1987. In those years the birth rates was constant about 10% and mortality rate was about 8%. We did not find significant phenomena of migration. The fertility rate in 1987 shows two peaks: the first at the age of 26-27 years, the second at the age of 31 years. Population distribution in age classes. We compared the population distribution in 1971 to the distribution in 1981. We found a decrease of 20% in population under 20 and an increase of 24% in population over 65 years. These increase is higher in females (relative increase of 62%) then in males (relative increase of 28%). Ages and death causes. The death age average in 1986-1987 is 67 years for males and 73 years for females. Under 65 years the more frequent and important death causes are neoplastic diseases (breast, lungs, alimentary tract), cardiovascular diseases, traffic accidents. We registered only 6% of deaths under 40 years of age.
我们研究了1980年至1987年的人口统计学情况以及1986 - 1987年伦巴第大区第12号地方卫生单位（USSL）人口的死因。该地方卫生单位面积60平方公里，有63,255名居民。出生率和死亡率。我们收集了1980年至1987年伦巴第大区第12号地方卫生单位各市政当局的出生、死亡、移民和迁出数据。在那些年里，出生率稳定在10%左右，死亡率约为8%。我们未发现显著的移民现象。1987年的生育率呈现两个峰值：第一个在26 - 27岁，第二个在31岁。各年龄段人口分布。我们将1971年的人口分布与1981年的进行了比较。我们发现20岁以下人口减少了20%，65岁以上人口增加了24%。女性的这一增长幅度（相对增长62%）高于男性（相对增长28%）。年龄与死因。1986 - 1987年男性的平均死亡年龄为67岁，女性为73岁。65岁以下人群中，较常见且重要的死因是肿瘤性疾病（乳腺癌、肺癌、消化道癌）、心血管疾病、交通事故。我们记录的40岁以下死亡人数仅占6%。
