Abstract

Urban population growth (non-agricultural population) in developing countries has
challenged the food security of urban households. The precise demographic definition of
urbanization is the increasing share of a nation's population living in urban areas (and thus a
declining share living in rural areas). Mostly, urbanization is the result of net rural to urban
migration. We investigated the food security among urban households and the effects and
various factors involved for the period of 1983 to 2012. Results showed that during this
period the food security of urban households had an increasing trend. Despite the
enhancement of food security among urban households, 5.6 percent of the urban
populations received less than necessary kilojoules level in 2012, role factors were
evaluated as well using time series pattern after estimation of urban household's aggregate
food security index (AHFSI). Results showed that effect lag variable of aggregate food
security index changes on growth of aggregate food security index in the next year will be
significantly negative (at 1% level). These results exhibited that with increase in one-unit
growth of food security index in one year, it would decrease by 0.008 units the next year.
Every one percent increase of people receiving less than standard energy level will decrease
the growth of food security index by 0.009 units. This finding is significant at 10 percent
level. Nevertheless, the 1st to 3rd five-year development plans showed more growths on
food security indices in comparison with the 4th development plan. Furthermore, the second
development plan showed the maximum increase of food security index in comparison with
the 4th development plan. Based on the results, the constant and steadily increasing trend of
the food security index should be considered as a priority in the future development plans
