all space everywhere is expanding at the same rate (which is increasing).
we know this because stars that are further away from us (lets say a few billion light years) have light that seems to have changed its energy over time, this means that the space which the light travels though has expanded, causing light with a specific wavelength (which is what determines it's energy) to transform into light with a wider wavelength (lower energy).
When we look at closer stars (lets say a few million light years away) we can see the same effect but to a greater extent. When we look at closer stars we are seeing newer light. Newer light is getting shifted more than the older light from the stars far away. this implies that the amout of shifting (space expansion) is increasing.
