Map 1: Medway

Medway Unitary Authority (“Medway”) was formed in 1998 and consists of five main towns (Strood, Rochester, Chatham, Gillingham, and Rainham) and a number of smaller towns and villages, now contained within 22 electoral wards. The built areas of the main towns have expanded over time and in places there is little demarcation between the end of one town and the beginning of another. The distance from the centre of one of these main towns to the next is between one and two miles.

The total area covered by Medway is 19,200 hectares (1 hectare is about the same size as an international rugby pitch or about one and half times the size of an international football pitch). While the towns are densely populated there are larger, much more sparsely populated rural areas in the Hoo Peninsula to the north of Medway, and the ward of Cuxton and Halling in the west. Parts of the Hoo Peninsula are within the North Kent Marshes, an environmentally significant wetlands region with several Sites of Special Scientific Interest (SSSIs).

There is one main hospital (“Acute Trust”), Medway NHS Foundation Trust, located about halfway between Chatham and Gillingham railway stations.

Population size

There were approximately 277,616 people resident in Medway in 2017, according to figures produced by the Office for National Statistics[1].

The 2017 mid-year population estimate shows an increase of 13,691 (5.2%) from the 2011 Census (263,925), and an increase of 28,128 (11.3%) since the Census in 2001 (249,488).

Compared to England the population of Medway has a smaller proportion of people over the age of 65 years (Medway 15.7% and England 18%). Medway has a larger proportion between the ages of 0 and 14 years than England (19.5% and 18.1% respectively) and between the ages of 15 and 24 years (9.6% and 9.3% respectively). The population of Medway is therefore younger than the population of England overall.

There are slightly more females than males (male to female sex ratio: 0.98).[1]

Population within Medway

At first glance Medway may appear to be largely homogenous, but this belies considerable variation. The largest ward is Gillingham North, with 19,883 people, and the smallest ward is Cuxton and Halling, with 6,222 people.[2]

There is considerable variation in population density, ranging from 1.8 people per hectare in Peninsula to 85.3 people per hectare in Gillingham South in 2011. The median density is 37 per hectare, and Rainham Central, Watling, and Strood South have approximately this density.[3]

The least densely populated wards are Peninsula, Cuxton and Halling and Strood Rural, and the most densely populated wards are Rochester East, Chatham Central and Gillingham South.

There are also differences in the age distributions of the ward populations as described below.

Wards with a population greater than 12,000: Gillingham North, Chatham Central, Gillingham South, Strood South, and Luton and Wayfield are the most populated wards in Medway and have a high proportion of younger people (ages 0-24). Rainham Central, Peninsula, Rochester South and Horsted, and Twydall have older populations. Strood Rural, Strood North, and Rainham South are large wards with a mix of young and older populations.[2]

Wards with a population smaller than 12,000: Princes Park, Rochester East, and Lordswood and Capstone have a younger age profile. Conversely Hempstead and Wigmore, Rainham North, Cuxton and Halling, Watling, Walderslade, and Rochester West have an older population. River ward is slightly unusual in terms of having a very high proportion of its population between 18 and 64 and also an above average proportion aged under 5.[2]

Mortality and life expectancy

Approximately 2,150 Medway residents die each year (2,197 deaths registered in 2017).[4] The all-age, all-cause mortality rate is statistically significantly higher in Medway than in both England and the South East (2015).[5]

The mortality rate among males is significantly higher than females; therefore the life expectancy is significantly higher in females than it is for males. Life expectancy from birth (a summary measure of current mortality patterns) in Medway is 3.5 years greater in females (82.3 years) than in males (78.8 years) over the period 2013 to 2017.[6]

There are also differences in life expectancy between the wards. Average life expectancy in Cuxton and Halling, Hempstead and Wigmore, Rainham Central, Lordswood and Capstone, and Rainham North is significantly greater than 10 wards including Chatham Central, Watling, and Gillingham South wards. Life expectancy is highest in Cuxton and Halling at 85.1 years, and lowest in Chatham Central at 78 years (2013 to 2017).[6]

In every ward life expectancy is greater in females than it is in males. The greatest difference in life expectancy is between females in Rainham Central (87.2 years) and males in River (75.8 years), a difference of 11.4 years (2013 to 2017).[6]


In 2016 there were 3,657 live births in Medway. The general fertility rate (GFR), a summary measure of fertility in women between the ages of 15 and 44 years, in Medway in 2016 was 66.2 births per 1,000. This value is higher than South East region and England averages (61.4 and 62.5 births per 1,000 respectively).[7]

The GFR varies considerably between the wards, ranging from around 52 in Watling to 78 in Luton and Wayfield (using data from 2014 to 2016). The five wards with the highest GFR are Luton and Wayfield, Peninsula, Chatham Central, Gillingham South, and Strood South. Areas with a higher GFR will need more children services and interventions to ensure that children have a healthy start in life.[8]

Teenage pregnancy is an important problem in Medway. The under-16 and under-18 conception rates are higher in Medway than the South East and National average, although there has been a general decrease over the past few years, both at a local and National level.

Between April and June 2016 the under-18 conception rate in Medway was 22.3 conceptions per 1,000 females aged 15–17. The average under-18 conception rate in England in the same period was 19.3 conceptions per 1,000. [9]

In 2015 Medway had an under-16 conception rate of 5.3 conceptions per 1,000 females aged 13–15 years compared to 2.9 per 1,000 (South East) and 3.7 per 1,000 (England). The proportion of conceptions to young women aged 13–15 years which lead to a termination of pregnancy is lower in Medway than nationally and in the South East. Just under half (44%) of conceptions, however, result in an abortion.[10]

Teenage pregnancy is covered in more detail in the Teenage pregnancy chapter in Children -> Teenage pregnancy.


Migration to Medway has dropped since peaking around 2011/12. For the first time in six years Medway saw an outward flow in internal migration - that is to other parts of the country - while international migration to Medway remained constant at +1,000 in 2016.

Neighbouring areas to Medway show the highest in and out migration flows: Swale, Maidstone, Gravesham then Tonbridge and Malling.

Migration flows to Medway originate from the west; just under two thirds of inward flows to Medway are via London, with flows from six South East London authorities representing just under half of all inflows to Medway: Bexley, Greenwich, Lewisham, Bromley, Croydon and Southwark.

The net migration flow to Medway from London has increased in recent years; the 2016 inward flow from the capital of 2,141 is 28% higher than in 2012.

There appears to be a younger flow into Medway than out, with a net inflow of younger migrants (0-15) and an outflow of older residents (65+). The outflow of working-age residents from Medway is notable.

The in and out flow of 19 to 20 year olds is significant, which is closely linked to moves for higher education. Outward moves are also notable around 23-25 years, which is likely linked to a combination of reasons; higher education, employment and or family age specific moves.[11]


In Medway, the percentage of pupils at the end of Key stage 4 achieving 5 plus A* to C grades, including English and Maths GCSEs, increased from 57.8% in 2014/15 to 60% in 2015/16. Medway remains above the national average of 53.5%.[12]


The majority of the population (89.6%) in Medway are classified as White, with the next largest ethnic group being Asian or Asian British (5.2%) including Chinese.[13] The proportion of the population that is White is slightly larger than in England and slightly lower than in Kent, although these differences are not significant. There are also no significant differences in ethnicity by gender.

Data from the January 2017 School Census shows that 81.5% of pupils in Medway are classified as White, with mixed ethnic origin being the second largest ethnic group (5.9%).[14] This may suggest a change in the overall population distribution in Medway since the 2011 Census.

Some wards are considerably more diverse than others. The three wards with the most ethnically diverse school populations are Chatham Central, Rochester East, and Gillingham North. Within these wards 53.8% to 62.9% of pupils are White British and at least 36.6% of pupils are of minority ethnic origins. Rainham South, Peninsula, and Cuxton and Halling are amongst the wards with the most homogenous school populations, as 86.7% to 89.1% of pupils are White British.[14]
