1. Population Characteristics

1.1 Population size, growth and density of population

The total population of Colombo district is 2,251,274. The intercensal

increase of population between 1981 and 2001 is 552,033 persons or 32.5 percent.

The growth rate of the district is 1.38 percent per annum during the above period.

The highest population is reported from Colombo divisional secretary's division and itis 380,946. The population of Padukka divisional secretary's division is 54,338 and it

is the divisional secretary's division with lowest population.

The urban sector of Colombo district comprised of four Municipal Councils

(Colombo, Dehiwala-Mount Lavinia, Moratuwa, Sri Jayawardanapura Kotte) and two

Urban Councils (Kolonnawa, Seethawakapura). Colombo Municipal Council

comprises of two divisional secretary's divisions viz. Colombo and Thimbirigasyaya.

Dehiwala-Mount Lavinia Municipal Council also comprises of two divisional

secretary's divisions viz. Dehiwala and Ratmalana. Moratuwa and Sri

Jayawardanapura Kotte Municipal Councils cover the total area of Moratuwa and SriJayawardanapura Kotte divisional secretary's divisions respectively.

The population of urban sector is 1,229,572 and it is 54.6 percent of the total

district population. Colombo Municipal Council is the largest and most densely

populated urban area in the district as well as in the country and it is more than half of 

the urban population in the district (52.6 percent). The rural and estate percentages

are 45.1 percent and 0.3 percent respectively. The estate population is concentrated in

Hanwella and Padukka divisional secretary's divisions only.

Colombo district has a land area of 676 square kilometres (sq.km). It has a

population density of 3,330 persons per sq.km. The value was 2,603 persons per sq.km.according to the census 1981. The population density of the urban area is 13,011 persons

per sq.km.

 1.2 Age-Sex composition

Age-sex composition of a population describes the pattern of the distribution

of people in different age and sex categories. It is determined by the past trends of

fertility, mortality and migration, which are the components of population change.

Figure 1 shows the age pyramid for Colombo district, which shows the distribution of

population by 5 year age groups and sex.

Page 2: Srilanka Population

Figure 1: Age Pyramid

One prominent feature of the age pyramid is the general decline in the population

below 20 with slight increases in 0-4 and 5-9 age groups compared to immediately

preceding age groups. The decline is mainly attributable to declining fertility levels. The

highest population is seen in 20-24 age group for both sexes. But in that age group males

are much higher than females. The pattern was the same in 1981 census. The population

is conveniently divided into three broad age groups; young (0-14 years), working age

(15-59 years) and old age (60 years and over). Percentages of these age groups are

shown in Table A together with the corresponding data for 1981.

Dependency Ratio 58.1 45.0

Percentage

It is clearly seen that the proportion of young population has declined

significantly by 8.3 percentage points during 1981–2001; on the other hand the

proportion of old age population has increased by 2.5 percentage points. Working age

population too shows an increase. The ratio of the population in the age groups 0-14

years and 60 years and over, to the population in the age group 15-59 years is called

dependency ratio. It is an approximation of the average number of dependants that each

person of working age must support. This is 45.0 percent in 2001. The corresponding

value for Colombo in 1981 was 58.1 percent. So, there is a significant decline in

dependency ratio during 1981-2001 period.

In Colombo district, the total number of males outnumber the females by 51,552.

Sex ratio, which is defined as the number of males per 100 females, is 104.7. It was

111.2 according to the previous census of 1981.

1.3 Ethnic Composition

The distribution of the population by major ethnic groups is shown in Table B and

reveals that the percentage decreased for Sinhalese by 1.0 percentage point. On the

otherhand, Sri Lanka Tamil population increased by the same magnitude but Indian

Tamil Population declined very marginally by 0.1 percentage points. An increase of 0.8

percentage points is seen among Sri Lanka Moors during 1981-2001. Malay population

decreased slightly from 1.3 percentage points to 1.0 percentage point.

1.5 Literacy, School attendance and Educational attainment

Ability to read and write at least one language was regarded as literate. The

literacy rates by sex is shown in Table D.

Literacy RateSex

The literacy rate of the population aged 10 years and over is 94.7 percent.

Literacy rate of males (95.3 percent) is higher than that of females (94.0 percent). Overall

rate has increased by 0.6 percentage points during 1981-2001.

Literacy rates in the two major languages, Sinhala and Tamil, are 83.6 percent and

19.4 percent respectively, in Colombo district. Nearly 33.1 percent of the population can

read and write English. These are shown in Figure 4 together with the ability to speak in

the three languages. Ability to speak English is slightly lower than the ability to read and

write English, in contrast to other two languages.

Literacy in a given language is predominantly determined by ethnic affiliations ofthe person. Table E shows the distribution of literate persons of different ethnic groups

by languages in which they are literate.

and 78.2 percent respectively and more than 35 percent of Sri Lanka Tamils and Indian

Page 8: Srilanka Population

7/21/2019 Srilanka Population

http://slidepdf.com/reader/full/srilanka-population 8/21

Tamils are literate in Sinhala. Literacy of Tamil is 78.4 percent for Sri Lanka Moor

community and significant percentage (54.9 percent) of them can read and write Sinhala.

Literacy in English is highest among Moors and lowest among Indian Tamils. Further,

literacy in English is higher among Sri Lanka Tamils than Sinhalese.

Ability of English language of people living in urban areas is higher compared to

rural and estate sectors; nearly 38 percent of urban residents can speak and read and write

English Language.

School Attendance

In this analysis, school attendance is regarded as attendence at any government or

recognized school which provides regular education for any number of grades from grade

1 to G.C.E. (A/L). Usually children in the age group 5-14 years are treated as the

population which should compulsorily be at school. Out of 315,776 children in the age

range 5-14 years, 274,717 children i.e nearly 87.0 percent are attending school as shown

in Table F. There is no significant difference between girls and boys.

As some of the children who completed age 5 by the census date could not get a

chance to enter schooling system in that year, it is more appropriate to consider age range

6-14 years as the group who should compulsorily be at school. A high proportion of 91.6

percent of children in 6-14 years are attending school in Colombo district. Here again

noticeable differentials do not exist between girls and boys. The average attendance of

15-19 year age group is 44.0 percentage points below that of 10-14 year age group. This

is expected as large numbers terminate their formal schooling during 15-19 age group

after G.C.E. (O/L) and G.C.E. (A/L) examinations. School attendance by single years of

age and sex is shown in Figure 5.

As shown in Figure 5 there is no appreciable drop in the level of attendance uptoabout age 14. It started to decline sharply after age 15. Although the boys and girls have

almost equal attendance upto around age 17, female attendance is higher in age 18 and 19

years.

Educational Attainment

The percentage distribution of population 5 years of age and over by educational

attainment is shown in Figure 6.

Ed1"ational attainments

Among the education categories shown in Figure 6, the highest percentage ofthe population (24.9) aged 5 years and over passed G.C.E. (O/L). Another 19.4

percent passed year 9-10; 15.3 percent passed year 6-8 and yet another 15.2 percent

recorded as completed their G.C.E. (A/L). Only 2.5 percent of the population aged 5

years and over record attainments with a degree and above.

There is no definite pattern in gender differences of educational attainment in

Colombo district. Upto year 8, education attainment of females are better than males; but

the pattern reverses for 'passed year 9-10' and G.C.E. (O/L)' categories. But higher

percentage of females (16.0 percent) passed G.C.E. (A/L) than males (14.4 percent).

Percentage of graduates are more prominent among males (2.8 percent) than females (2.2

percent).

1.6 Labour Force Participation

Economically active population or the labour force comprised of employed and

unemployed persons. The proportion of the economically active population to the total

population aged 10 years and over is called the labour force participation rate. It is 48.4

percent for Colombo district. Female labour force participation rate (28.6 percent) is

very much lower than the males (67.6 percent). Labour force participation rates

computed for five year age groups provide a more refined measure as the overall ratedepends on the age composition of the population.

The male age specific labour force participation rates are higher than females

for all ages. The labour force participation of children in 10-14 age group is very

small for both sexes. More than 69 percent of the male population of 20-59 age

group are economically active and they reach the peak value of 91.5 percent in the

35-39 age group. The sharp increase of female participation rate can be seen upto age

20-24 and it decreases gradually thereafter. The peak value of 46.6 percent can be

seen for 20-24 age group.

The economically inactive rate is highest (98.1 percent) for 10-14 age group. As

expected 94.4 percent of them are students.

Unemployment

The total number of unemployed population in the district is 57,089. Majority ofthem (62.8 percent) are males. Percentage distribution of unemployed persons by age

number of unemployed males exceed that of females, unemployment rate of females (8.0percent) is higher than that of males (5.5 percent). Age specific unemployment rates

reveal that the unemployment rate is very high for 15-19 and 20-24 age groups. Nearly

24 percent of the labour force in the age group 15-19 and nearly 15 percent of the 20-24

age group are unemployed. It is also seen that female rates are higher than the male rates

at all age groups excluding 15-19.

expected females are getting married earlier than males. For example, among females in

25-29 age group only 35.6 percent are never married but the corresponding percentage is

as high as 57.5 percent for males. These patterns are reflected in singulate mean age at

first marriage, which stands at 25.0 years for females and 28.5 years for males. The

corresponding values for 1981 were 25.5 years and 28.9 years respectively.

1.8 Fertility

Mean number of children ever born is an indicator of cumulative fertility. Mean

number of children ever born for ever married women aged 15 years and over is 2.3. Its

distribution by five year age groups of ever married women is shown in Figure 10.
