Sub-city and other areas

Sub-city areas used in our data on Southampton Data Observatory include:

  • Electoral wards (17 wards each with three councillors). More information on wards is available on the Southampton City Council website
  • Middle Layer Super Output Areas (MSOA) – part of the Office for National Statistics geographical hierarchy for reporting small area statistics. MSOA are the highest level and have a minimum size of 5,000 residents and 2,000 households with an average population size of 7,800
  • Lower Level Super Output Areas (LSOA) – part of the Office for National Statistics geographical hierarchy for reporting small area statistics. LSOA are the middle level and have an average population of 1,500 people or 650 households. Most commonly used for deprivation comparisons
  • Output Areas (OA) – part of the Office for National Statistics geographical hierarchy for reporting small area statistics. OA are the smallest area and have an average population of about 310 residents
  • Index of Multiple Deprivation - a measure of relative deprivation for small areas (Lower Super Output Areas (LSOA). It is a combined measure of deprivation based on a total of 37 separate indicators that have been grouped into seven domains, each of which reflects a different aspect of deprivation experienced by individuals living in an area.
  • GP surgeries – data is often recorded at GP surgery areas
  • Primary Care Networks (PCN) - each of the 1,250 PCNs across England are based on GP registered patient lists, typically serving natural communities of between 30,000 to 50,000 people (with some flexibility). They are small enough to provide the personal care valued by both people and GPs, but large enough to have impact and economies of scale through better collaboration between GP practices and others in the local health and social care system. These areas are non- geographical areas. More information is available on the NHS England website.
  • Local Enterprise Partnerships (LEPs) - are voluntary partnerships between local authorities and businesses, straddling multiple local authorities to help determine local economic priorities

Terms used

Below is a list of terms and language used on the Southampton Data Observatory:

Age-standardization

A statistical technique used to compare populations with different age structures, in which the characteristics of the populations are statistically transformed to match those of a reference population. Useful because relative over- or under-representation of different age groups can obscure comparisons of age-dependent diseases (e.g., ischemic heart disease or malaria) across populations.

Alcohol hospital admissions

Alcohol-related hospital admissions can be used as a measure to indicate the burden of excessive alcohol consumption on the health of a population. Three hospital admissions measures can be used: alcohol-specific, alcohol-related (narrow) and alcohol-related (broad):

Alcohol-related admissions

Alcohol-related admissions are those which can partly be attributed to alcohol

  • The broad definition encompasses admissions where the primary or secondary diagnoses is an alcohol-related condition
  • The narrow definition only includes admissions where the primary diagnosis is alcohol-related

Alcohol-specific hospital admissions

Alcohol-specific hospital admissions are where the primary or any of the secondary diagnoses are wholly attributable to alcohol

Anonymisation

The process of rendering data into a form which does not identify individuals and where there is little or no risk of identification (identification is not likely to take place).

Body mass index (BMI)

The body mass index (BMI) is a measure that uses your height and weight to work out if your weight is healthy. The BMI calculation divides an adult's weight in kilograms by their height in metres squared. For example, A BMI of 25 means 25kg/m2. More information on BMI is available on the NHS website (BMI).

Caldicott Guardian

A senior person responsible for protecting the confidentiality of patient and service user information and enabling appropriate information sharing.

Confidence intervals

A confidence interval is a range of values that is used to quantify the imprecision in the estimate of a particular indicator. Specifically, it quantifies the imprecision that results from random variation in the measurement of the indicator. A wider confidence interval shows that the indicator value presented is likely to be a less precise estimate of the true underlying value. More information is available in the APHO Technical Briefing 3: Commonly used public health statistics and their confidence intervals

Crude rate

Crude rates are the simplest types of rates dividing the number that something occurred for by the total population the event could have happened for. Unlike more complex age standardised rates which adjusts for the age structure of the population.

Crude birth rate

Crude birth rate is the number of live births per 1,000 population of all ages, not adjusted for age or sex

Directly standardised rate (DSR)

The direct method of standardisation requires that the age-specific rates for all populations being studied are available and that a standard population is defined.

Disability-adjusted life years (DALYs)

The sum of years lost due to premature death (Years of life lost) and years lived with disability (YLDs). DALYs are also defined as years of healthy life lost.

Disability free life expectancy

The number of years that a person is expected to continue to live in a healthy condition.

Drug use or misuse

Southampton City Council is using the term use rather than misuse because using stigmatising language reinforces negative stereotypes. Person-centred language focuses on the person, not their substance use.

General fertility rate (GFR)

General fertility rate is the number of live births per 1,000 female population aged 15 to 44 years, calculated using ONS mid- year population estimates.

Gross Domestic Product (GDP)

GDP is the total monetary or market value of all the finished goods and services produced within a country’s borders in a specific time period. As a broad measure of overall domestic production, it functions as a comprehensive scorecard of a given country’s economic health

Gross Value Added (GVA)

GVA is the value generated by any unit engaged in the production of goods and services. How much is produced.

Healthy life expectancy

Healthy life expectancy is the number of years that a person at a given age can expect to live in good health, taking into account mortality and disability. Also see life expectancy.

High blood pressure

Blood pressure is recorded with 2 numbers. The systolic pressure (higher number) is the force at which your heart pumps blood around your body. The diastolic pressure (lower number) is the resistance to the blood flow in the blood vessels between heartbeats. Measured in millimetres of mercury (mmHg). Generally high blood pressure is considered to be from 140/90mmHg (or an average of 135/85mmHg at home) – or 150/90mmHg (or an average of 145/85mmHg at home) if the person is aged over 80 years. For more information on blood pressure see

Incidence

The number of new cases of a given disease during a given period in a specified population. It also is used for the rate at which new events occur in a defined population. It is differentiated from prevalence, which refers to all cases, new or old, in the population at a given time. Also see prevalence.

Number of years a person is expected to live based on their present age. For example, life expectancy at birth. More information on life expectancy is available on the life expectancy page and from the Office for National Statistics -Life expectancy website.

Prevalence

Prevalence is the proportion of a population who have a specific characteristic in a given time period. In medicine, a measure of the total number of people in a specific group who have (or had) a certain disease, condition, or risk factor (such as smoking or obesity) at a specific point in time or during a given period of time. Also see incidence.

Proportion

The number of people with a specific condition or attribute at a specified time divided by the total number of people in the population. The number or proportion of cases, events or conditions in a given population. The same as percent of.

Pseudonymisation

Pseudonymisation is a procedure by which identifying fields (that is, names, dates of birth and addresses) within a data record are replaced by one or more artificial identifiers to protect the privacy of individuals.

Quinary age groups

Five- year age groups, normally running from 0-4 to 90+

Quintiles

The first quintile represents the lowest 1/5 of values from 0-20% of the range. The second quintile includes the values from 20-40%, the third quintile includes 40-60%, the fourth quintile includes 60-80%, and the fifth quintile includes the highest 1/5 of values from 80-100%.

Replacement level fertility

Replacement level fertility is the average number of children born per woman at which a population exactly replaces itself from one generation to the next, without migration.

Standard deviation or standard error

Standard deviation or standard error is the statistical measure of the amount of variation around the mean of a distribution. It is defined as the square root of the variance. By convention, the term ‘standard deviation’ is used only when the distribution is describing variation in individual values within a population or sample. The standard deviation of a summary measure, such as the sample mean, is known as the ‘standard error’.

Statistically significant

The Southampton Data Observatory uses 95% confidence intervals For example a 95% confidence interval of 47-53, means if researchers or analysts did the same study or analyses over and over and over again with samples of the whole population, they would get results between 47 and 53 exactly 95% of the time. More information is available in the APHO Technical Briefing 3: Commonly used public health statistics and their confidence intervals

Total Fertility rate (TFR)

The total fertility rate is the average number of live children that a group of women would bear if they experienced the age-specific fertility rates of the calendar year throughout their childbearing lifespan. For more information see the World Health Organisation website.

Variance

Variance is the statistical measure of the amount of variation around the mean of a distribution. The greater the variance the more widely distributed are the observed values.

Years of life lost (YLL)

Years of life lost is a measure of premature mortality that takes into account both the frequency of deaths and the age at which it occurs. Based on number of deaths below the age of 75, and the potential number of years that the person could have lived.

Years lived with disability (YLD)

Years of life lived with any short-term or long-term health loss.

Z-score

Z-score is a statistical measurement that describes a value's relationship to the mean of a group of values. Z-score is measured in terms of standard deviations from the mean. If a Z-score is 0, it indicates that the data point's score is identical to the mean score.
