The number of maternal deaths and maternal mortality rates for selected causes, 2000 to most recent year.

For most of human history, pregnancy and childbirth were very risky; mothers would die in at least 1 in 100 pregnancies.1

Since the average woman would have at least four or five children, the lifetime risk of dying from maternal causes would be at least 1 in 25.2 This was true everywhere.

Thankfully, that’s no longer the case. We’ve made huge strides in not only protecting infants in childbirth and the early stages of their lives, but we’ve also made it much safer for women.

But we’re not done yet. There are still huge inequalities in the risks of pregnancy across the world. Pregnant women in countries like Sierra Leone and Kenya are around 100 times more likely to die during pregnancy or childbirth than those in countries like Norway, Sweden, or Germany.3 But it doesn’t have to be this way. We could save hundreds of thousands of lives a year by closing these gaps.

I’ve compared three scenarios in the chart below to clarify these points.

First, we can see that the situation today is awful. 286,000 women died from maternal causes in 2020.4 That’s 784 deaths per day on average, or one mother dying every two minutes.5

Second, we can consider the very high maternal mortality rates of the past. Particularly good long-term data is available for Finland or Sweden, which shows that in 1750, around 900 women died per 100,000 live births.6 Since there were 135 million births in 2020, I calculate that 1.2 million women would have died from maternal causes that year if these rates hadn’t improved.7 Things are much, much better than they used to be.

Finally, things can still be much better. We know this because some countries have maternal mortality rates that are far lower than the global average. And they all used to be in a similar position to the worst-off countries today. In Europe, the maternal mortality rate was 8 deaths per 100,000 live births in 2020. That’s around 25 times lower than the global average.8 If all countries could achieve the same outcomes as Europe, 11,000 women would have died from maternal causes in 2020 — a small fraction of the 286,000 deaths that occurred.9

Providing the best conditions for women everywhere would reduce the global death toll by 275,000 maternal deaths a year.

This dataset contains counts of live births for California counties based on information entered on birth certificates. Final counts are derived from static data and include out of state births to California residents, whereas provisional counts are derived from incomplete and dynamic data. Provisional counts are based on the records available when the data was retrieved and may not represent all births that occurred during the time period.

The final data tables include both births that occurred in California regardless of the place of residence (by occurrence) and births to California residents (by residence), whereas the provisional data table only includes births that occurred in California regardless of the place of residence (by occurrence). The data are reported as totals, as well as stratified by parent giving birth's age, parent giving birth's race-ethnicity, and birth place type. See temporal coverage for more information on which strata are available for which years.

Number and percentage of live births and fetal deaths (stillbirths), by place of birth (hospital or non-hospital), 1991 to most recent year.

In 2023, non-Hispanic Black women had the highest rates of maternal mortality among select races/ethnicities in the United States, with 50.3 deaths per 100,000 live births. The total maternal mortality rate in the U.S. at that time was 18.6 per 100,000 live births, a decrease from a rate of almost 33 in 2021. This statistic presents the maternal mortality rates in the United States from 2018 to 2023, by race and ethnicity.

The Mortality - Infant Deaths (from Linked Birth / Infant Death Records) online databases on CDC WONDER provide counts and rates for deaths of children under 1 year of age, occuring within the United States to U.S. residents. Information from death certificates has been linked to corresponding birth certificates. Data are available by county of mother's residence, child's age, underlying cause of death, sex, birth weight, birth plurality, birth order, gestational age at birth, period of prenatal care, maternal race and ethnicity, maternal age, maternal education and marital status. Data are available since 1995. The data are produced by the National Center for Health Statistics.

Collective data of Japan's birth-related statistics from 1899 to 2022. Some data are missing between the years 1944 and 1946 due to records lost during World War II.

E-Stat Demographic Survey

The dataset contains information on various demographic and health indicators for different countries. It is organized into several columns, each providing essential information about these countries. Here's a description of each column:

1. Country: This column represents the names of different countries or regions included in the dataset. Each row corresponds to a specific country or region, and this column serves as the identifier for each entry.

2. Life Expectancy Males: This column contains data on the average life expectancy of males in each of the listed countries. Life expectancy is a crucial health indicator and provides an estimate of the average number of years a male can expect to live, given current mortality rates and health conditions.

3. Life Expectancy Females: Similar to the "Life Expectancy Males" column, this column provides data on the average life expectancy of females in the same countries. It reflects the average number of years a female can expect to live, considering the prevailing health and mortality conditions.

4. Birth Rate: The "Birth Rate" column contains information about the birth rate in each country. Birth rate is a demographic indicator that represents the number of live births per 1,000 people in a given population over a specific period, usually a year. It can provide insights into a country's population growth or decline.

5. Death Rate: This column presents data on the death rate in each of the listed countries. The death rate is another crucial demographic indicator and represents the number of deaths per 1,000 people in a population over a specific period, often a year. It helps gauge the overall health and mortality conditions within a country.

Abstract: This study analyzed the occurrence of severe maternal morbidity, the most frequent diagnostic criteria, and the quality of obstetric care in public hospitals in Ribeirão Preto, São Paulo State, Brazil. A quantitative surveillance survey of severe maternal morbidity used World Health Organization (WHO) criteria for potentially life-threatening conditions and maternal near miss. Cases were identified from August 1, 2015, to February 2, 2016. The sample included 259 women with severe maternal morbidity (potentially life-threatening conditions/maternal near miss) during the gestational and postpartum cycle, hospitalized for childbirth in the four public institutions providing obstetric care in the city. The descriptive analysis was based on absolute and relative rates of diagnostic criteria for potentially life-threatening conditions and maternal near miss, besides description of the women in the sample (sociodemographic characteristics, obstetric history, and prenatal and childbirth care). Quality of care indicators set by the WHO based on morbimortality were also calculated. There were 3,497 deliveries, 3,502 live births in all the hospitals in the city, two maternal deaths, and 19 maternal near miss. Maternal near miss ratio was 5.4 cases per 1,000 live births, and the maternal mortality ratio was 57.1 deaths per 100,000 live birth. The mortality rate among cases with severe maternal outcome (maternal near miss plus maternal death) was 9.5%. The study revealed important potentially life-threatening conditions and maternal near miss rates. The occurrence of deaths from hemorrhagic causes highlights the need to improve the quality of obstetric care. The findings can potentially help improve local policy for obstetric care.

Number of infant deaths and infant mortality rates, by age group (neonatal and post-neonatal), 1991 to most recent year.

This dataset of U.S. mortality trends since 1900 highlights the differences in age-adjusted death rates and life expectancy at birth by race and sex. Age-adjusted death rates (deaths per 100,000) after 1998 are calculated based on the 2000 U.S. standard population. Populations used for computing death rates for 2011–2017 are postcensal estimates based on the 2010 census, estimated as of July 1, 2010. Rates for census years are based on populations enumerated in the corresponding censuses. Rates for noncensus years between 2000 and 2010 are revised using updated intercensal population estimates and may differ from rates previously published. Data on age-adjusted death rates prior to 1999 are taken from historical data (see References below). Life expectancy data are available up to 2017. Due to changes in categories of race used in publications, data are not available for the black population consistently before 1968, and not at all before 1960. More information on historical data on age-adjusted death rates is available at https://www.cdc.gov/nchs/nvss/mortality/hist293.htm.

Abstract Objective To study the structure ofmaternalmortality caused by abortion in the Tula region. Methods The medical records of deceased pregnant women, childbirth, and postpartum from January 01, 2001, to December 31, 2015, were analyzed. Results Overall, 204,095 abortion cases were recorded in the Tula region for over 15 years. The frequency of abortion was reduced 4-fold, with 18,200 in 2001 to 4,538 in 2015. The rate of abortions per 1,000 women (age 15-44 years) for 15 years decreased by 40.5%, that is, from 46.53 (2001) to 18.84 (2015), and that of abortions per 100 live births and stillbirths was 29.5%, that is, from 161.7 (2001) to 41.5 (2015). Five women died from abortion complications that began outside of the hospital, which accounted for 0.01% of the total number. In the structure of causes of maternal mortality for 15 years, abortion represented 14.3% of the cases. Lethality mainly occurred in the period from 2001 to 2005 (4 cases). Among thematernal deaths, many women died in rural areas after pregnancy termination at 18 to 20 weeks of gestation (n = 4). In addition, three women died from sepsis and two from bleeding. Conclusion The introduction of modern, effective technologies of family planning has reduced maternal mortality due to abortion.

This is a publication on maternity activity in English NHS hospitals. This report examines data relating to delivery and birth episodes in 2023-24, and the booking appointments for these deliveries. This annual publication covers the financial year ending March 2024. Data is included from both the Hospital Episodes Statistics (HES) data warehouse and the Maternity Services Data Set (MSDS). HES contains records of all admissions, appointments and attendances for patients admitted to NHS hospitals in England. The HES data used in this publication are called 'delivery episodes'. The MSDS collects records of each stage of the maternity service care pathway in NHS-funded maternity services, and includes information not recorded in HES. The MSDS is a maturing, national-level dataset. In April 2019, the MSDS transitioned to a new version of the dataset. This version, MSDS v2.0, is an update that introduced a new structure and content - including clinical terminology, in order to meet current clinical practice and incorporate new requirements. It is designed to meet requirements that resulted from the National Maternity Review, which led to the publication of the Better Births report in February 2016. This is the fifth publication of data from MSDS v2.0 and data from 2019-20 onwards is not directly comparable to data from previous years. This publication shows the number of HES delivery episodes during the period, with a number of breakdowns including by method of onset of labour, delivery method and place of delivery. It also shows the number of MSDS deliveries recorded during the period, with a breakdown for the mother's smoking status at the booking appointment by age group. It also provides counts of live born term babies with breakdowns for the general condition of newborns (via Apgar scores), skin-to-skin contact and baby's first feed type - all immediately after birth. There is also data available in a separate file on breastfeeding at 6 to 8 weeks. For the first time information on 'Smoking at Time of Delivery' has been presented using annual data from the MSDS. This includes national data broken down by maternal age, ethnicity and deprivation. From 2025/2026, MSDS will become the official source of 'Smoking at Time of Delivery' information and will replace the historic 'Smoking at Time of Delivery' data which is to become retired. We are currently undergoing dual collection and reporting on a quarterly basis for 2024/25 to help users compare information from the two sources. We are working with data submitters to help reconcile any discrepancies at a local level before any close down activities begin. A link to the dual reporting in the SATOD publication series can be found in the links below. Information on how all measures are constructed can be found in the HES Metadata and MSDS Metadata files provided below. In this publication we have also included an interactive Power BI dashboard to enable users to explore key NHS Maternity Statistics measures. The purpose of this publication is to inform and support strategic and policy-led processes for the benefit of patient care. This report will also be of interest to researchers, journalists and members of the public interested in NHS hospital activity in England. Any feedback on this publication or dashboard can be provided to enquiries@nhsdigital.nhs.uk, under the subject “NHS Maternity Statistics”.

This dataset contains counts of live births for California as a whole based on information entered on birth certificates. Final counts are derived from static data and include out of state births to California residents, whereas provisional counts are derived from incomplete and dynamic data. Provisional counts are based on the records available when the data was retrieved and may not represent all births that occurred during the time period.

The final data tables include both births that occurred in California regardless of the place of residence (by occurrence) and births to California residents (by residence), whereas the provisional data table only includes births that occurred in California regardless of the place of residence (by occurrence). The data are reported as totals, as well as stratified by parent giving birth's age, parent giving birth's race-ethnicity, and birth place type. See temporal coverage for more information on which strata are available for which years.

Listening to Mothers™ surveys (2002 - to present) investigate women's childbearing experiences from pregnancy (and sometimes earlier) through the postpartum period, and their views about these matters. National Listening to Mothers surveys to date were led by Childbirth Connection, which became a core program of the National Partnership for Women & Families in 2014. Listening to Mothers in California, led by the National Partnership for Women & Families, is the first state-level Listening to Mothers survey. This population-based survey of women who gave birth in California hospitals in 2016 was carried out by core Listening to Mothers investigators at the National Partnership for Women & Families and at Boston University School of Public Health, joined by investigators at what is now known as the University of California San Francisco Center for Health Equity, in collaboration with the survey research firm Quantum Market Research. California Health Care Foundation and Yellow Chair Foundation funded the survey. As investigators had access to selected birth certificate items for sampling, contacting sampled women, data weighting and data analyses, the methodology of this survey differs from the methodology used in national Listening to Mothers surveys. Other differences between past national surveys and this state-level survey include the ability to participate in the state survey in either English or Spanish and to participate on any device, as well as with a trained interviewer. Eligible women could participate in past national surveys in English only and either on their own with a laptop or desktop computer or by telephone with a trained interviewer. The Listening to Mothers in California survey questionnaire retained some core items that had been included in previous surveys, adapted others (including for mobile-first display), and included new items developed to explore the evolving U.S. health and maternity care environment and topics relevant to the California context. Topics included care arrangements, maternity care (and especially care during the hospital stay for giving birth), mode of birth, respectful and disrespectful treatment, postpartum experiences, and perinatal mental health (especially anxiety and depression). The public dataset is limited to items provided by survey participants while completing the survey, exclusive of personally identifiable information. For their analyses, the survey investigators have access to two additional sources of information about survey participants that cannot be made public: selected items on participants’ birth certificates and selected items abstracted from the California Department of Health Care Services Management Information System/Decision Support System Warehouse. Much information about the California survey is available at either www.nationalpartnership.org/LTMCA or www.chcf.org/listening-to-mothers-CA. Information about national surveys (including a bibliography of analyses carried out to date and other reports) is available at www.nationalpartnership.org/listeningtomothers/.
