So – the number is in, and the questions (I’m sure) are on their way. The Census released population figures from the 2010 Census yesterday as part of the redistricting process yesterday!
LA County’s population increased by only 299,267 people between 2000 and 2010, from 9,519,338 to 9,818,605. Still a lot of people!
Here are a couple of initial files that were sent to me:

Personally, I’ve been quoting a figure above 10 million for a while now. My assumption is that we had a bell curve – that we gained many more people until the recession, where we lost population. Anecdotally, I believe that the northern part of our County (Palmdale, Lancaster, etc) was the center of growth for a while – this is perhaps where we lost of lot of people too.
My thoughts initially are to do both a spatial and a temporal analysis – showing changes in time and space. What is the best way to do this? What would you look at?
Have fun – lots more data to come!

Its quite amazing to see such a small increase for such a large and a populous county over a period of 10 years. Its also interesting to see the increase in number of census tracts over the same time period indicating re-distribution of the population rather than real growth. Your suggested spatial and temporal analysis should reveal that very nicely. Look forward to it.
