  2. Evaluation of 1993 Census Data Presented by: Somaia Khalid Elkhair Omer Director of Field work Operation5th Population Census

  3. Sudan Population Density 1993 Largest Country in Africa 2.5 mio km² Population 25 mio person Average population density 9.8 person/km² Density: Khartoum State 169 person/km² Northern State 3 person/km² Area of Sudan 600 mio Feddan Agricultural Land 200 mio Feddan Non- Agricultural Land 180 mio Feddan Forests 220 mio Feddan Population density 26.5 person/km² (respect to Agricultural Land)

  4. Population Census in Sudan First census 1955/6 Second census 1973 Third census 1983 Fourth census 1993 Fifth census 2008

  5. Evaluation of 4th Census 1993 Care was taken to collect information as accurate as possible there are expected errors in the data (arising from a number of sources) Due to resource constraints a PES could not be carried out Therefore it was proposed to examine the results of the 1993 census with regard to its coverage and contents by:  comparison with 1983 census  application of various analytical techniques (testing consistency of results)

  6. Evaluation of Census Data Growth Rate Sex Ratio AgeDistribution

  7. Growth Rate Total Sudan GR 2.89 North Sudan GR 3.22 N. Sudan Settled 4.39 N. Sudan nomads -11.4

  8. Evaluation of Growth Rate • GR for Sudan as a whole is consistent with our expectations • GR in Red Sea state is -0.76 for males + 0.49 for females under count of nomadic population in 1993 census or over count of nomadic population in 1983 census Excluding the nomad GR in Red Sea is 6.5 • The GR rate for the remaining Northern states are acceptable

  9. Sex Ratio Sex Ratio in Sudan  SR in 1955 is 102  SR in 1973 is 102  SR in 1983 is 104  SR in 1993 is 101  SR in 2008 is 103  The Sex Ratio:- follow a consistent pattern

  10. Nomadic Population Growth Rate for Nomad:

  11. Nomadic Population • The frame for the census count of nomads was the list provided by the nomadic sheikhs • The (-)ve GR observed for 1983-1993 implies:  the 83 figures of nomads is on the high side or  due to under count or miss classification of nomadic population as settled population

  12. Age Distribution • Age is often estimated:  by the enumerator or  by the respondent themselves on the basis of historical events • 1993 census indicated:  strong preference for certain digits ending 0 and 5  lesser extend digits ending 2 and 8  avoiding odd digits such as 1,3,7,9

  13. Age Distribution Measures of age heaping: Whipples Index:- Sex 1983 1993 Males 280.0 255.7 Females 286.3 279.5 Index shows that age data for Sudan should be regarded as very rough Age data for females is less accurate than for males

  14. Age Distribution Myer’s Index: Sex MI 83 MI 93 Males 27.9 24.4 Females 28.8 28.0 MI for Sudan is higher than: Zambia India Libya which are close to 10 (indicating greater inaccuracy in age reporting)
