Coverage
Geographic Coverage
Chi Linh is a mountainous town of Hai Duong Province of northern Vietnam. Chi Linh town covers an area of 300,54 square kilometers, contains 17 communes and 3 towns and has a population of 142,278 (50.3% female, 49.7% male). A number of different ethnic minority groups live in the district, including San Diu, Chinese, H'Mong, Tay, Nung and some other ethnic minorities. The population density varies across the district, with higher density in lowland communes and places with access to transportation routes. Approximately 25% of the total population lives in urban areas. The number of adolescents between 15-24 years of age accounts for 19.3% of the total district population according to 1999 population data. Residents receive information, including health information, from several different channels: 100% of the communes/towns are covered with the loud-speaker system; 100% of households have their own radio receivers; about 60% of households have TVs.
Several national roads as well as inter-communal roads run through the town. While the national roads are high quality and therefore can handle a high volume of high speed traffic, the inter-communal roads are ill-maintained due to insufficient funding. As a result, some communes are not very easily accessible. Much of the land in Chi Linh is used for agriculture, including rice and subsidiary dry crop cultivation. In addition, forest resources in the district are currently being exploited. The town also contains two thermal power plants as well as a medical glass plant, a refractory soil mine, and a leather shoe making plant providing employment in the district.
