Meanwhile, figures from the Office for National Statistics published in July show immigration fuelled the biggest rise in the population of England and Wales for at least 75 years.
The population rose by almost 610,000 to 60.9 million between mid-2022 and the middle of last year – the biggest increase since 1949, when comparable records began.
The ONS said the growth was largely down to record levels of net migration, which stood at 622,000 for the year to mid-2023.
A West Midlands Police spokesman said: “We are investigating after graffiti was sprayed at locations around the Alum Rock area.

“We are working with the local authority to ensure it is promptly removed.
“Anyone who can help with our investigation can contact us via Live Chat on our website, or by calling 101, quoting crime reference 20/632434/24.”
