About StreetSignal

Neighbourhood intelligence built on open data. Designed to scale across African cities.

StreetSignal brings together safety statistics, school outcomes, property valuations, transport connectivity, healthcare access, and municipal service data at suburb level. Starting with all 744 Cape Town suburbs as our pilot city. Free, with every calculation published and every source disclosed.

The data that affects where you live should not be locked behind a paywall or buried in government PDFs.

Who StreetSignal is for

Whether you are buying your first home, comparing suburbs for a family move, assessing an investment property, or choosing a school for your child - StreetSignal gives you the same data, for every suburb, for free.

The platform is designed for homebuyers comparing neighbourhoods, property investors analysing growth trends, parents researching schools, insurance professionals assessing area risk, and journalists and researchers working with neighbourhood-level data.

What StreetSignal does

Buying a home is a 20-year decision. StreetSignal gives you the data behind it: safety, schools, property values, household conditions, municipal responsiveness, transport connectivity, and health and amenities. In Cape Town, our pilot city, that means 744 suburbs. Coverage varies by dimension - safety data covers 734 suburbs, transport connectivity 637, household conditions 407 - and every page discloses exactly what data is and is not available. Instead of relying on anecdote, marketing, or word of mouth, you can compare neighbourhoods on the same evidence base.

Each suburb page brings together data from multiple government sources into a single profile, with every calculation explained and every limitation disclosed.

How the data is processed

StreetSignal processes raw government datasets through a series of ingestion and computation steps. Crime statistics from 63 police precincts are mapped to 744 suburbs via a crosswalk that neither SAPS nor the City publishes. Valuation roll records are aggregated into median bands and growth rates. Household survey responses are transformed into composite indices covering service delivery, housing quality, economic structure, and food security. More than 2.5 million municipal service requests are scored for responsiveness.

The result is a set of structured data files that power every page on the platform. When new data is published, the pipeline reruns and the entire site refreshes.

Every page is pre-built and served from a global CDN. There are no loading spinners, no client-side data fetching, and no accounts required.

Data sources

City of Cape Town Open Data Portal

General Valuation Roll covering 744 suburbs with property values and physical profiles. The 2024 Household Survey sampling 8,318 households across 407 suburbs. The C3 Service Request System comprising more than 2.5 million logged complaints, used to compute civic responsiveness metrics.

South African Police Service

Crime statistics by precinct covering 63 precincts and 35 offence categories. StreetSignal's suburb-to-precinct crosswalk maps 734 of 744 suburbs to their primary SAPS precinct, an alignment that neither SAPS nor the City publishes natively.

Department of Basic Education

School locations and quintile classifications for 344 suburbs, plus 2025 National Senior Certificate results for 157 suburbs. Schools are matched to suburbs by geographic point-in-polygon intersection. Pass rates are Buhlmann credibility-weighted (a statistical technique that prevents small cohorts from producing misleading averages) with k=50 to stabilise estimates for suburbs with few matric candidates.

Statistics South Africa

Census 2022 population estimates, used for per-capita normalisation of crime rates and service delivery metrics.

City of Cape Town: Development Focus Areas

27 priority investment zones from the District Spatial Development Framework (January 2023). 43 of 744 suburbs fall within a designated Development Focus Area, signalling committed City investment in infrastructure, services, and economic opportunity.

City of Cape Town: New Development Areas

836 land parcels earmarked for future development, classified by intended land use (residential, mixed use, industrial, commercial, public service). 244 of 744 suburbs contain at least one designated development parcel.

City of Cape Town: Prepaid Electricity

Prepaid electricity data by suburb and tariff (January 2024 to February 2026). Free basic electricity proportion computed for 357 suburbs, indicating the reach of the City's indigent support programme.

City of Cape Town: Health Care Facilities

157 healthcare facilities (public clinics, Community Day Centres, provincial hospitals, and private facilities) used to compute nearest-facility distances and within-5km counts for 744 suburbs.

City of Cape Town: Places of Worship

1,645 places of worship matched to suburbs via the ADR_SBRB field, grouped by religion type (Christian, Islamic, Jewish, Hindu, Other). Coverage: 299 of 744 suburbs.

What makes StreetSignal different

Neutral aggregator. StreetSignal has no estate agent affiliations and no commercial incentive to present any suburb more favourably than the data warrants. When a neighbourhood has a high crime rate, low service delivery, or poor school outcomes, the page says so.

A free suburb-level neighbourhood intelligence platform for South Africa. Real estate uses suburbs (744 boundaries). Police use precincts (60 boundaries). These do not align. Most publicly available tools operate at precinct or ward level, and commercial platforms that do offer suburb-level data are typically paywalled. StreetSignal's proprietary suburb-to-precinct crosswalk solves the boundary mismatch, integrating data from the City of Cape Town Open Data Portal, SAPS crime statistics, the Department of Basic Education, and Statistics South Africa Census 2022 into suburb-level intelligence across safety, property valuations, school outcomes, municipal service delivery, transport, and household conditions.

Free to use. Every suburb profile, every data point, every comparison is available without registration, subscription, or paywall. The data that affects where you live should not be locked behind a price tag.

Full transparency. Every safety index, service delivery index, and economic indicator has a published formula. The methodology page explains how each metric is computed, what weights are applied, and what the limitations are.

Ethical data framing. Historically under-invested neighbourhoods are presented with structural context. Where socioeconomic indicators reflect the legacy of apartheid-era spatial planning, the page says so, without deficit language and without empty optimism. Both challenges and strengths are shown.

Designed for portability

The methodology is city-agnostic. StreetSignal requires three data inputs to cover a new city: a municipal valuation roll, crime statistics with geographic boundaries, and a household-level survey. Cape Town was chosen as the pilot because its Open Data Portal provides all three at suburb-level granularity. The computation logic, indices, and page architecture are designed to be reusable across any city where comparable open data exists.

Our responsibility with neighbourhood data

Neighbourhood data in post-apartheid South Africa requires particular attention to equity. Suburb-level scores can function as proxies for race given the spatial engineering of the Group Areas Act. StreetSignal takes this seriously.

Every metric is contextualised with structural causes. Where a suburb's data reflects historical under-investment, the page names the system, not the community. Challenges are presented alongside strengths. No suburb page shows only negative indicators.

StreetSignal data must not be used for insurance pricing, credit scoring, tenant screening, or any form of geographic discrimination. The platform serves all 744 suburbs equally, from Camps Bay to Khayelitsha, with the same transparency and the same respect.

We are committed to the principles of the Promotion of Equality and Prevention of Unfair Discrimination Act (PEPUDA). Our terms of use prohibit discriminatory applications of the data we publish.

Who built this

StreetSignal was created by Kuziva Muzondo - a Zimbabwean-born programme manager based in the UK, who grew up in South Africa from the age of seven. East London for school, Gqeberha for university, Johannesburg and London for work. South Africa shaped how he thinks about cities: who gets access to what, which neighbourhoods get investment, and how much of that is visible to the people making decisions about where to live.

The commercial side is handled by Emmanuel Nhliziyo, a Chartered Accountant also from Zimbabwe, raised in South Africa. They have been friends for 26 years.

StreetSignal launched in late February 2026 after Kuziva found the City of Cape Town's Open Data Portal and realised the foundation was already there. The City had done the hard part - publishing the data. Somebody just needed to connect the dots.

The platform is not affiliated with the City of Cape Town, any estate agency, any property developer, or any insurance company.

How this is funded

StreetSignal is a personal project with no external funding, no advertising revenue, and no data sales. The site is hosted on Cloudflare Pages. The data is sourced from freely available government datasets. There is no catch.
