This bulletin presents estimated annual conceptions occurring to women usually resident in England and Wales in 2012. Conception statistics bring together records of birth registrations collected under the Births and Deaths Registration Act (1953) and abortion notifications received under the Abortion Act (1967), amended by the Human Fertilisation and Embryology Act (2008). They include all pregnancies of women usually resident in England and Wales which lead to one of the following outcomes:
a maternity registered in England and Wales at which one or more live births or stillbirths occur
a termination of a pregnancy by abortion under the 1967 Act, which takes place in England and Wales
Conception statistics do not include conceptions resulting in miscarriages or illegal abortions (see background note 1).
Conceptions are analysed primarily using numbers, rates and the percentage leading to abortion. The statistics are tabulated by age, area of usual residence of woman and marital status.
This is the first time that the Office for National Statistics (ONS) has published annual 2012 statistics on conceptions for women usually resident in England and Wales.
To meet user needs, timely but provisional quarterly conception statistics are published in the Vital Statistics: Population and Health Reference Tables. The figures provided are the number of conceptions, the conception rate and the percentage of conceptions leading to abortion, by age, year and quarter for England, Wales and England and Wales. Provisional quarterly conceptions to women aged under 18 are also published by area of usual residence to enable monitoring by local authorities of teenage pregnancy levels.
An explanation of the difference between provisional and final data is included in the metadata published as part of the Vital Statistics: Population and Health Reference Tables.Nôl i'r tabl cynnwys
In 2012, the estimated number of conceptions in England and Wales fell by 2.7% to 884,748 from 909,109 in 2011. The number of conceptions rose between 2001 and 2010 despite a slight fall in 2008. Since 2010 the number of conceptions has fallen from a peak of 909,245 conceptions.
Prior to 1969, the first full year for which abortions data are available, the number of conceptions was equivalent to the number of maternities. Following the introduction of the Abortion Act (1967) the number of conceptions increased (Figure 1). The sudden decline in conceptions in the early to mid 1970s, despite a rise in the number of women in childbearing ages could be explained by the increased use of contraception (Wellings and Kane, 1999). Oral contraception was introduced in 1961, but this was only available to married women and was a chargeable prescription. In 1970 there was a mandate for family planning clinics to start treating single women. In 1974 contraception became free on the National Health Service (NHS), opening up services to women regardless of marital status and ability to pay.
There have been a number of scares about the safety of the contraceptive pill (Wellings and Kane, 1999). These scares deterred some women from using the pill as a method of contraception due to concerns about their health (Wood et al, 1997). This may have led to a number of women using less reliable methods of contraception or no contraception at all. These pill scares correspond to increases in the number of conceptions and occurred in 1976-77, 1983, 1986 and 1995-96.
The gradual increase in conceptions between 2001 and 2010 results from an overall increase in the number of conceptions at all ages with the exception of those aged under 20. Factors influencing the increasing age at conception are explored in a later section.
The conception rate for 2012 has decreased to 78.5 conceptions per thousand women aged 15-44, from 80.4 in 2011, a decrease of 2.4%. The proportion of all conceptions resulting in a maternity in 2012 was 79%, unchanged from 2011. This proportion has remained fairly stable over the last two decades.
The size of the female population of child bearing age (women aged 15-44) will influence the number of conceptions. The composition of the female population will also influence the number of conceptions as there are peak age groups for maternities (25-29 and 30-34) and abortions (20-24) and the relative sizes of these groups will impact upon the number of conceptions. Changes in the size of the population are determined by births of females in previous years, mortality and migration.
The fall in the overall conception rate between 2011 and 2012 was driven by a 2.7% decrease in the number of conceptions and would have fallen further had there not been a 0.3% fall in the female population of child bearing age.Nôl i'r tabl cynnwys
There has been a long-term rise in the proportion of conceptions (and births) occurring outside marriage. In 2012 conceptions outside of a marriage/civil partnership accounted for 57% of all conceptions in England and Wales, compared with 54% in 2002 and 44% in 1992. In 2012 the proportion of conceptions outside marriage/civil partnership which resulted in a maternity was 69%, compared with 92% of conceptions inside marriage/civil partnership.Nôl i'r tabl cynnwys
Between 2011 and 2012 conception rates increased for women aged 35 years and over, and decreased for women aged under 35 years.
The largest percentage increase in conception rates occurred among women aged 35-39 (1.0%). A smaller increase in conception rates was recorded among women aged 40 and over (0.7%). Conception rates for women aged under 20 and 20-24 decreased by 9.6% and 5.5% respectively. Rates for women aged 25-29 and 30-34 decreased by smaller amounts (1.5% and 2.3% respectively).
The conception rate for women aged 40 and over has more than doubled since 1990 (Figure 2) from 6.6 to 14.0 conceptions per thousand women. The number of women in this age group conceiving has risen from 12,032 in 1990 to almost 29,000 in 2011 and 2012. For women aged 40 and over, the percentage of conceptions leading to abortion fell from 43% in 1990 to 28% in 2010, 2011 and 2012. The number of conceptions, the conception rate and the percentage of conceptions leading to abortion for women aged 40 and over have remained relatively stable in 2012, compared with 2011.
The conception rate for women aged 35-39 has seen similar increases, almost doubling since 1990. The 30-34 age group is the youngest age group in which conception rates have risen almost continuously since 1990, rising by over a third.
Reasons for an increased number of women conceiving at ages 30 and above include increased participation in higher education; increased female participation in the labour force, the increasing importance of a career, the rising opportunity costs of childbearing, labour market uncertainty, housing factors and instability of partnerships ( Jefferies, 2008 (297 Kb Pdf) ; Ní Bhrolcháin, 2012).
The conception rate for women aged under 20 fell by 9.6% to 44.2 conceptions per thousand women aged 15-19 in 2012 (from 48.9 in 2011). This continues the overall downward trend in the conception rate for women aged under 20 since 2007 from 61.4 conceptions per thousand women. In 2012 conceptions to women aged under 18 accounted for 37% of all conceptions to women aged under 20, unchanged from 2011.
In 2012 there were 27,834 conceptions to women aged under 18 compared with 31,051 in 2011, a decrease of 10%. This is the lowest number of conceptions in this age group since 1969. Nearly half (49%) of all conceptions to women aged under 18 in 2012 led to an abortion, this proportion has remained relatively unchanged since 2006.
The under 18 conception rate for England and Wales was 27.9 in 2012 compared with 30.9 in 2011, a decrease of 9.7%. This is the lowest estimated under 18 conception rate since comparable conception statistics were first produced in 1969. This fall in the conception rate in 2012 can be attributed to similar falls in the conception rate leading to abortion and the conception rate leading to a maternity (decreases of 9.9% and 9.5% respectively). The under 18 conception rate continues the overall decline recorded since 1998 when there were 47.1 conceptions per thousand women aged 15-17, despite slight increases in 2002 and 2007. Since 1998 the conception rate for women aged under 18 has decreased by 41%.
The number of conceptions to girls aged under 16 decreased by 9.3% from 5,991 in 2011 to 5,432 in 2012. A similar decline can also be seen in the conception rate for girls aged under 16. In 2012 there were 5.6 conceptions per thousand girls aged 13-15 compared with 6.1 in 2011, a decrease of 8.2%. This fall in the conception rate consists of an 11% fall in the rate of conceptions leading to abortion and an 8.3% fall in the rate of conceptions leading to a maternity. The percentage of conceptions leading to abortion for this age group has remained at 60% since 2011.
Overall the under 16 conception rate has decreased since 2007 from 8.1 conceptions per thousand girls aged 13-15 to 5.6 in 2012. The under 16 conception rate is the lowest since 1969, the first year for which we have comparable data, when a rate of 6.9 conceptions per thousand girls aged 13-15 was recorded. Nearly three-quarters (72%) of under 16 conceptions in 2012 were to girls aged 15.
There are a number of factors which could explain recent reductions in teenage conceptions, including:
- the programs invested in by successive governments (for example sex and relationships education, improved access to contraceptives and contraceptive publicity)
- a shift in aspirations of young women towards education (Broecke and Hamed, 2008)
- the perception of stigma associated with being a teenage mother (McDermott et al, 2004)
It is widely understood that teenage pregnancy and early motherhood can be associated with poor educational achievement, poor physical and mental health, social isolation, poverty and related factors. There is also a growing recognition that socio-economic disadvantage can be both a cause and a consequence of teenage motherhood (Swann et al, 2003).
In England this led the previous Government to set a target to halve the teenage conception rate by 2010, when compared with 1998. Local authorities set ten year strategies in place, aiming to reduce the local rate between 40% and 60%. These local targets were to help underpin the national 50% reduction target. The Teenage Pregnancy Strategy ended in 2010; however teenage pregnancy has remained an area of policy interest. The current Government has included the under 18 teenage conception rate as one of its three sexual health indicators in its Public Health Outcomes Framework (2013-2016) and it is one of the national measures of progress on child poverty. This ensures a continued focus on preventing teenage conceptions as well as the social impact upon teenage mothers.
In Wales, teenage conception rates are widely used as outcome indicators in the sexual health context, for example in the Sexual Health and Well-being Action Plan for Wales, 2010-15, as well as being a general indicator of health and inequality, for example in Our Healthy Future. The conception rate for under 18 years is the most commonly used indicator with the underage rate (under 16 years) being a key health indicator for children and young people.Nôl i'r tabl cynnwys
The percentage of conceptions leading to a legal abortion varies by age group. Women aged 30-34 have had the lowest percentage of conceptions leading to abortion. In 2012, 13% of conceptions to women aged 30-34 resulted in an abortion.
Over the last two decades the percentage of conceptions leading to a legal abortion has generally increased for women aged under 20 but decreased for women aged 35 and over (Figure 4). For women in their twenties and early thirties the percentage of conceptions leading to abortion generally increased between 1992 and 2001, but decreased steadily until 2009-2010 before increasing slightly again.
In 2012, the percentage of conceptions leading to a legal abortion decreased slightly for under 18s but increased for the under 20s. All age groups 20 and above either increased, or experienced no change from 2011.

For women usually resident in England, the overall conception rate fell by 2.4% from 80.7 conceptions per thousand women aged 15-44 in 2011 to 78.8 in 2012. For women usually resident in Wales, the overall conception rate fell by 1.7% from 75.1 conceptions per thousand women aged 15-44 in 2011 to 73.8 in 2012.
A comparison of rates across regions in England for all ages shows that the North East had the lowest conception rate in 2012, with 71.7 conceptions per thousand women aged 15-44. London had the highest overall conception rate at 86.7.Nôl i'r tabl cynnwys
For women usually resident in England the under 18 conception rate fell by 9.8% from 30.7 conceptions per thousand women aged 15-17 in 2011 to 27.7 in 2012. A decrease was also recorded for women usually resident in Wales where the under 18 conception rate fell by 9.9% from 34.2 conceptions per thousand women aged 15-17 in 2011 to 30.8 in 2012. In 1998, the under 18 conception rate in England was 46.6 conceptions per thousand women aged 15-17. A comparison of under 18 conception rates for England and Wales can be seen in Figure 5.
A comparison of rates across regions in England shows that the North East had the highest under 18 conception rate in 2012, with 35.5 per thousand women aged 15-17. The South East and the East both had the lowest rate for women aged under 18 in 2012 with 23.2 per thousand women aged 15-17.
It should be noted that at the local level, statistics for under 18 conceptions can fluctuate between years (due to an unusually high or low number of teenage conceptions in a year).
A comparison of under 18 conception rates across local authorities is illustrated in Figure 6.

As can be seen from the map (Figure 6) there is significant variation in the conception rate at the local level. When analysing figures for areas with small populations, for example Rutland UA, it is important to also take into account the numbers involved, as a slight change when numbers are small can lead to large changes in the rate. Other population characteristics can also have an impact, for example, the ethnic composition of an area, the level of deprivation and educational attainment levels.
There has been widespread variation in the success of local authorities in reducing teenage conception rates since 1998, as can be seen in Table 6 (701.5 Kb Excel sheet) .Nôl i'r tabl cynnwys
The Department of Health (DH) leads for the Government on reducing under 18 conceptions and is a key user of conception statistics. DH monitor the rate of under 18 conceptions under the Public Health Outcomes Framework 2013-2016 as part of the measures of health improvement. DH uses the numbers of conceptions at all ages as a marker for the success of policies on access to contraception (and other sexual health services). DH uses conception statistics by age because they are of use to maternity service providers, particularly during the antenatal period, to allow them to plan for the level of demand for antenatal services.
DH published their Framework for Sexual Health Improvement in England in 2013. The framework is designed to be used by local organisations, including local authorities and health and wellbeing boards, to help them provide the best sexual health services in their area. It sets out a number of ambitions for sexual health, including the need for a fall in the number of unwanted pregnancies and offering counselling to all women who request an abortion so they can discuss the options and choices available with a trained counsellor.
Public Health England (PHE) is another key user of conception statistics. PHE have a role in providing information and evidence to local areas, as well as providing more tailored advice and support. Data, information, tools and resources (including policy, practice and research) are brought together in a single knowledge hub, for use by local decision makers.
In Wales teenage conception rates are used widely as outcome indicators in the sexual health context, for example in the Sexual Health and Well-being Action Plan for Wales, 2010-15, as well as being a general indicator of health and health inequality, for example in Our Healthy Future. The conception rate for under 18 years is the most commonly used with the underage rate (under 16 years) being a key health indicator for children and young people. See for example Child Poverty targets.
Local authorities use the data, particularly the number and rate of under 18 conceptions to feed into their Joint Strategic Needs Assessments and to inform their commissioning decisions. They also use the statistics to make comparisons with other local areas and with the county, region and national level.
Voluntary and community sector organisations, particularly those working in the field of sexual health, use the statistics to inform their work with local areas.Nôl i'r tabl cynnwys
