I went up to New York and spoke with Barry Ritholtz on his Masters in Business podcast. Some links: The podcast A transcript Bloomberg View: Every Graph Tells a Story I am really glad I got the chance to chat with Barry and share some of my story. Have a listen if you want to learn more about my work and background, the mortgage finance industry, and how I use data visualization.
I really like R, but I love the R community. Since I’ve started using R intensively in the past couple of years, I’ve constantly been awed and inspired by all the amazing things that people are doing with R. The spirit of the open source community and people’s willingness to share their thoughts and code is fantastic. Many times in this space we’ve remixed different data visualizations with R, often relying on awesome new packages that others have developed.
At the start of the year, the R package gganimate hit CRAN. See this announcement blog post with some examples. In this space, I’ve shared several posts on animation see tags. But I haven’t been using gganimate. Instead, I took a more direct approach building the animations via loops and trying to tween directly if I wanted a smooth animation. This level of control is nice, but frankly the defaults in gganimate work better than many of my attempts to hand craft it.
It’s the time of the year where everybody is dusting off their crystal balls and peering into the future. There’s even still time to send out your “Winter is Coming” newsletter. Let’s take a step back and look at how forecasts of U.S. macro variables have evolved. Is forecasting still hard? Last year we looked at historical forecasts of economic conditions in the post forecasting is hard. Let’s update it.
My recent economic and housing market talks see for example here have been titled: “Will the U.S. housing market get back on track in 2019?”. My general conclusion has been cautiously optimistic. There is enough strength in the broader economy and enough of a tailwind from demographic forces to push the U.S. housing market to modest growth next year. I still think that’s true, but as I have said in my talks, risks are weighted to the downside.
The year is winding down, and folks are starting to think about next year. With lots of folks reviewing strategic plans and whatnot, there’s increased demand for me to talk about my 2019 economic outlook. Over on LinkedIn I posted a summary of my most recent chartbook: Will the housing market get back on track in 2019?. Do check it out. Slidecraft For these slides I used a mixture of R and Excel.
U.S. housing markets have slowed down in 2018. Housing construction, which is still running well below both historical averages and what the U.S. currently needs to meet rising demand has stalled out this year. The current level of housing construction is close to the level we’ve seen in recession periods. And the historical comparison stretching back decades is comparing a nation with significantly fewer households. Total U.S. households for example, in 1970 were about 1/2 (63 million) of what they were in 2017 (126 million) FRED chart.
Supply and demand, isoquants, indifference, the lists goes on. Economists love curves. One attracting extra attention these days is the Phillips curve. Last week I was in Boston for the annual meeting of the National Association for Business Economics (NABE). The overall conference was quite good, and certainly one of the highlights was a lunchtime speech by Federal Reserve Chairman Jerome Powell. You can find the speech here (pdf).
In this post I want review some trends in U.S. housing supply and demand. Specifically I want to look at county level trends in population, housing supply (the total number of housing units) and house prices. We’ll uncover some interesting trends. Per usual we will make our graphics with R. Preparing the data required several steps that I will outline in a follow up post. For now we’ll just proceed with the data I’ve put together.
It’s been a while since I posted here. I’ve got some longer form things in the works, but let’s ease back into it. Let’s take a look at the latest Job Openings and Labor Turnover Survey (JOLTS) data via the U.S. Bureau of Labor Statistics. This post is an update of this post. Per usual we will make our graphics with R. First, let’s look at aggregate trends.
