According to global statistics, the world's elderly population is growing. Based on the statistics of the national census Bureaus, the population of elderly over the year 1355 to 1390 has increased 3٫5 times and it is predicted that the population of elderlywill experience a growth of 23٪ in 1429, while it was 6٫6٪ in 1375. As age grows, significant physiological and mental changes appear. These changes cause the aged to perceive the physical environment different and respond them differently. Research This is a theoretical library research investigating and taking advantage of valuable sources. The key questions include 1) How is theaging processinIran? 2) What changes in the city spaces are required to fit the needs of elderlies? Investigating the theoretical foundations regarding the issue under questionand presenting needed factors which are pro-elderly, the study suggests that our current city spaces do not meet the needs of our elderlies. Nor they full fill the needs of healthy young people. The main causes include designing issues, ineffective urban management, lack of maintenance and bad implementation of city plans which has brought about unsuitable city spaces. The major problems of city spaces include: 1)the narrowed walkways 2)the slipperiness of the floors 3) the piles of building materials on walkways 4)different levels of floors in pathways 5) floors made up ofdirt or sand. The city spacesshould be designed in such a way that consider disability inthe elderly. Based on the studies conducted in England, some needed factors have been highlighted, which can be a useful model in our country in urban design. These include: Familiar environment, readability, availability, recognizability, comfort and security.

Mortality is one of indicators of socio - economic development and is an important factor in determining population growth. The aim of this study is to investigate the causes and patterns of mortality in Hazrat Vali AsrHospital of Mamasani Nurabad city in 1360 to 1385. After reviewing theprevious studies In this context, the review of the demographic theories related to research topic including: population transition theories, the theory of social and economic development associated with mortality, medical technology development theory and the theory of epidemiology in transitionare infocus. For this study, data from 850 cases of dead people during the 25 years in Vali Asr hospitalbeenanalyzed. Analysis shows a clear view of the pattern of mortality and changes during the years 1360 to 1385. The descriptive results of present study is about the causes of mortality during the years 1360 to 1385 and compare it, to the extent is consistent with epidemiology Omran theory. According to our evaluation, infectious and parasitic diseases decreasedin 1385compared to1360. In fact, during the past 25 years, with the development of medical and public health conditions, infectious and parasitic diseases, thatspreadinpoorand unfavorable conditions of health, reduced. The final results of this study show that epidemiology changes has become of the infectious and parasitic diseases to chronic diseases.

In 1990, half of the world's population lived in urban areas. This phenomenon is increasing worldwide. Due to the excess supply of labor in rural areas, villagers have migrated to the cities, especially big cities. This percentage has increased urbanization on a global scale. Urbanization in Iran during the past few decades has undergone many changes. Uneven distribution of population and activities in the area of the land is an important factor in regional imbalances. This phenomenon has various problems in terms of distribution facilities and services created andthis is felt more in the less developed regions. In this paper, the issue of urbanization and its influencing factors were studied. Then, according to statistical analysis, expectedrelationshipsbetween the issues have been considered. Distribution of resources and development indicators are the most important factors on the distribution, population density and Immigration influence in society. This study has shown that Provincesof thecountrywhich have higherpossibilitiesand are often developed provincesurbanizationalsoincreases.

Migration is the main causes of population change and the most important external factor influencing the number and structure of the population. Attention, understanding and careful analysis of the migration process in different regions of a country and consequently estimate the population size and age and sexual structure orientation in the future of the region, to meetthe needs of future generations, can make a plan to achieve greater executive power. In this study, internal migration flows in the period 1385-1390 is examined. The research methodis secondary analysis of data from General Population and Housing Census of 1390. Results of the study shows that of a total of 5534666 people been displaced within the country's borders, 92 percent of them, their previous residential places were inside the country. Of the total number of internal migration were, 60/3 percent from town to town, 12/87 percent from villages to towns, 14/84percent from towns to villages, and 7/24 percent from villages to villages and 0٫99 percent not to mention their previous residence. The migrants abroad and arrived in Tehran province are ranked first. During thisperiod, Alborz Province (4٫12), Semnan (2٫99), Bushehr (2٫52), Yazd (2٫51) had the highest net annual migration and Lorestan (2٫06), Kermanshah (1٫99), Chaharmahal and Bakhtiari (1٫89), Sistan and Baluchestan (1٫35) had the lowest ratio of annual net migration. During this period, the lowest proportion of immigrants in the province of Kermanshah (-286), and the highest ratio is in Alborz province (1830).

Civil Registration law and regulations since 96 years ago had emphasized on in time registration of vital events. The process of registration of an event (birth or death) divided in two fields, declaration and registration. Registration of vital events is the Civil Registration Organization (CRO) duty and for declaration, legal declarer is responsible. According to CRO law the declarers can be individuals and legal entities. Late registration is the effects of out of legal time declaration by individuals or legal entities. Due to prevention of late registration of vital events, CRO intervene indeclaration field by performing an extra ordinary activities to finding the events and invite the responsible person to declare the event to CRO offices or mobile registrar. The present paper has a new approach to the issue of late registration, tried to explain the reasons from a different aspects.

There are three factorswhich are very important in each planning which consists of population, space and place, and the association of population with space and place. Population asone of thethree elementsaffectstheplanning. The number of population alone cannot be effective. But what are important are population characteristics, including sex ratio, age composition, educational status, employment, distributionand diffusionofgeographical spaceand thegrowth anddynamismof the place. Kerman province is one of the low density provincesof our country, because a low population is distributed in a large extension, So that the province has about 3٫5 percent of the population, while more than 11 percent of the country's area is allocated to the province. Low density, the uneven distribution of the population in a wide range, large variation in urban andrural population growth, rapid urban population growth, negative growth in the rural population, is the most important issuesof the province's population. The purpose of this study is to show the population status, especially the urban population, inequality in the distribution of the urbanpopulation in different cities of the province and the overall imbalance in population distribution in the province. Methodology in this research is descriptive-analytical. Usingavailable resources, demographicinformation of thecities of the provinceprovided, the populationnumbersclassified, analysis andidentificationprocessis recognized in order to be used in planning. Results of the study show that low density, unbalanced distribution of urban and rural population, the rapid growth of urban population and the increasing number of cities are among population characteristics of Kerman province. In the end some strategies are given in order to settle province population issues.
